1Note: this file lists major user-visible changes only. 2 3* Changes in Quagga 0.99.24 4 5User-visible changes: 6- [pimd] New daemon: pimd provides IPv4 PIM-SSM multicast routing. 7- [bgpd] New feature: "next-hop-self all" to override nexthop on iBGP route 8 reflector setups. 9- [bgpd] route-maps have a new action "set ipv6 next-hop peer-address" 10- [bgpd] route-maps have a new action "set as-path prepend last-as" 11- [bgpd] Update validity checking (particularly MP-BGP / IPv6 routes) was 12 touched up significantly. Please report possible bugs. 13- [ripd] New feature: RIP for IPv4 now supports equal-cost multipath (ECMP) 14- [zebra] Multicast RIB support has been extended. It still is IPv4 only. 15- [zebra] "no link-detect" is now printed in configurations since it won't 16 be the default anymore soon. To retain current behaviour, re-save your 17 configuration after updating to 0.99.24. 18 19Distributor-visible changes: 20- --enable-pimd is added to enable pimd. It is considered experimental, though 21 unless the distribution target is embedded systems with little flash, there 22 is no reason to not include it in packages. 23- --disable-ipv6 no longer exists as an option. It's 2015, your C library 24 really needs to have IPv6 support by now. 25- --disable-netlink no longer exists as an option. It didn't work anyway. 26- --disable-solaris no longer exists as an option. It only controlled some 27 init scripts. 28- --enable-isisd is now the default. 29- mrlg.cgi is no longer included (it was severely outdated). It can be found 30 independently at http://mrlg.op-sec.us/ 31- build on Linux with the musl C library should now work 32 33* Changes in Quagga 0.99.23 34 35Known issues: 36- [bgpd] setting an extcommunity in a route map on a route that already has 37 an extcommunity attribute will cause bgpd to crash. This issue will be 38 fixed in a followup minor release. 39 40User-visible changes: 41- [lib] Performance enhancements on hashes and timers. 42- [bgpd] New feature: iBGP TTL security. 43- [bgpd] New feature: relaxed bestpath criteria for multipath and improved 44 display of multipath routes in "show ip bgp". Scripts parsing this output 45 may need to be updated. 46- [bgpd] Multiprotocol peerings over IPv6 now try to find a more appropriate 47 IPv4 nexthop by looking at the interface. 48- [ospf6d] A large amount of changes has been merged for ospf6d. Careful 49 evaluation prior to deployment is recommended. 50- [zebra] Recursive route support has been overhauled. Scripts parsing 51 "show ip route" output may need adaptation. 52- [zebra] IPv6 address management has been improved regarding tentative 53 addresses. This is visible in that a freshly configured address will not 54 immediately be marked as usable. 55- [*] a lot of bugs have been fixed, please refer to the git log 56 57* Changes in Quagga 0.99.22 58 59- [bgpd] The semantics of default-originate route-map have changed. 60 The route-map is now used to advertise the default route conditionally. 61 The old behaviour which allowed to set attributes on the originated 62 default route is no longer supported. 63- [bgpd] There is now a replace-as option to neighbor ... local-as ... 64 no-prepend. For details, refer to the user documentation. 65- [zebra] An FPM interface has been added. This provides an alternate 66 interface to routing information and is geared at OpenFlow & co. 67- [snmp] AgentX is now supported; the old smux backend is considered 68 deprecated. ospf6d has also had OSPFV3-MIB added. 69- [*] several issues with configuration save/load/apply have been fixed, 70 in particular on ospf "max-metric router-lsa administrative" and 71 "distribute-list", bgpd "no neighbor activate", isisd "metric-style", 72- [*] a lot of bugs have been fixed, please refer to the git log 73 74* Changes in Quagga 0.99.21 75 76- [bgpd] BGP multipath support has been merged 77- [bgpd] SAFI (Multicast topology) support has been extended to propagate 78 the topology to zebra. 79- [bgpd] AS path limit functionality has been removed 80- [babeld] a new routing daemon implementing the BABEL ad-hoc mesh routing 81 protocol has been merged. 82- [isisd] a major overhaul has been picked up. Please note that isisd is 83 STILL NOT SUITABLE FOR PRODUCTION USE. 84- [*] a lot of bugs have been fixed, please refer to the git log 85 86* Changes in Quagga 0.99.10 87 88- [bgpd] 4-byte AS support added 89- [bgpd] MRT format changes to version 2. Those relying on 90 bgpd MRT table dumps may need to update their tools. 91- [bgpd] Added new route-map set statement: "as-path exclude" 92- Zebra RIB updates queue has evolved into a multi-level 93 structure to address RIB consistency issues. 94 95* Changes in Quagga 0.99.2 96 97- [bgpd] Work queues added to bgpd to split up update processing, 98 particularly beneficial when a peer session goes down. AS_PATH 99 parsing rewritten to be clearer, more robust and ready for 4-byte. 100 101- [ripd] Simple authentication is no longer the default authentication 102 mode for ripd. The default is now no-authentication. Any setups which 103 used simple authentication will probably need to update their 104 configuration manually. 105 106- [ospfd] 1s dead-interval with sub-second Hellos feature added. 107 SPF timers now specified in milliseconds, and with adaptive 108 hold-time support. RFC3137 Stub-router support added. Default ABR 109 type is now 'cisco'. 110 111- Solaris least privileges support added. 112 113* Changes in Quagga 0.99.1 114 115- Zserv is now buffered via threads and non-blocking in most cases for both 116 clients and zebra, which should improve responsiveness of daemons when 117 they must send many messages to zebra. 118 119- 'show thread cpu' now displays both cpu+system and wall-clock time, 120 where getrusage() is available. 121 122- Background threads added and workqueue API added, with a 123 'show work-queues' command. Thread scheduling improved slightly. 124 125- Zebra now has a work-queue for RIB processing. See 'show work-queues' in 126 the zebra daemon vty. 127 128- Support for interface renaming on Linux netlink systems. 129 130- GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip 131 route-source" command. 132 133- Automatic logging of backtraces should daemons crash to assist in 134 diagnosis. See the documentation for more information on configuring 135 logging correctly, and set --enable-gcc-rdynamic if compiling with gcc. 136 137* Changes in Quagga 0.98.0 138 139- Logging facilities upgraded. One can now specify a severity level 140 for each logging destination. And a new "show logging" command gives 141 thorough information on the current logging system configuration. 142 143- Watchquagga daemon added. This is not well tested yet. Please try 144 monitor mode first before enabling restart features. It is important 145 to make sure that the various timers are configured with appropriate 146 values for your site. 147 148- BGP route-server support added. See the texinfo documentation. 149 150- OSPF API initialisation is disabled by default even if compiled in. You 151 can enable it with -a/--apiserver command line switch. 152 153- "write-config integrated" vtysh command replaced with "service 154 integrated-vtysh-config" command. 155 156- Router id is now handled by zebra daemon and all daemons receive changes 157 from it. Router id can be overriden in daemons' configurations of course. 158 To fix common router id in zebra daemon you can either install non-127 159 address on loopback or use "router-id x.x.x.x" command. 160 161- "secondary" keyword is removed from ip address configuration. All 162 supported OS'es have their own vision what's secondary address and 163 how to handle it. 164 165- Zebra no longer enables forwarding by default. If you rely on zebra to 166 enable forwarding make sure to add '<ip|ip6> forwarding' statements 167 to your zebra configuration file. 168 169- All libraries are built and used shared, on platforms where libtool 170 supports shared libraries. 171 172- Router advertisement syntax is changed. In usual cases (if you didn't do 173 any fancy stuff) it's enough to change lines in configuration from: 174 "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link" 175 to: 176 "ipv6 nd prefix X:X:X:X::/X" 177 178 All router advertisement options are documented in texi documentation. 179 180- --enable-nssa configure switch is removed. NSSA support is stable enough. 181 182- Daemons don't look at current directory for config file any more. 183 184* Changes in Quagga 0.96.5 185 186- include files are installed in $(prefix)/include/quagga. Programs 187 building against these includes should -I$(prefix)/include and e.g. 188 #include <quagga/routemap.h> 189 190- New option --enable-exampledir puts example files in a separate 191 directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules 192 compliance. 193 194- New configure options --enable-configfile-mask and 195 --enable-logfile-mask to set umask values for config and log 196 values. Masks default to 0600, matching previous behavior. 197 198- Import current CVS isisd from SourceForge, then merge it with 199 the Quagga's Framework. 200 201* Changes in Quagga 0.96.4 202 203- Further fixes to ospfd, some relating to the PtP revert. Interface 204lookups should be a lot more robust now. 205 206- Fix for a remote triggerable crash in vty layer. 207 208- Improvements to ripd, and addition of split horizon support. 209 210- Improved bgpd table support, now dumps at time of day intervals rather 211than time from startup intervals. Much improved support for IPv6 table 212dumps. show commands for views improved. 213 214* Changes in Quagga 0.96.3 215 216- revert the 'generic PtP' patch. Means Quagga will no longer work with 217FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs 218which the PtP patch introduced. 219 220* Changes in Quagga 0.96.2 221 222- Fix crash in ospfd 223 224* Changes in Quagga 0.96.1 225 226- Iron out problem with the privileges definitions 227 228* Changes in Quagga 0.96 229 230- Privilege support, daemons now run with the minimal privileges needed, see 231 the documentation for details. 232 233- NSSA ABR support in ospfd. 234 235- OSPF-API support merged in. 236 237- 6WIND patch merged in. 238 239* Changes in zebra-0.93 240 241* Changes in bgpd 242 243** Configuration is changed to new format. 244 245* Changes in ospfd 246 247** Crush bugs which reported on Zebra ML is fixed. 248 249** Opaque LSA and TE LSA support is added by KDD R&D Laboratories, 250 Inc. 251 252* Chages in ospf6d 253 254** Many bugs are fixed. 255 256* Changes in zebra-0.92a 257 258* Changes in bgpd 259 260** Fix "^$" community list bug. 261 262** Below command's Address Family specific configurations are added 263 264 nexthop-self 265 route-reflector-client 266 route-server-client 267 soft-reconfiguration inbound 268 269* Changes in zebra 270 271** Treat kernel type routes as EGP routes. 272 273* Changes in zebra-0.92 274 275** Overall security is improved. Default umask is 0077. 276 277* Changes in ripd 278 279** If output interface is in simple password authentication mode, 280substruct one from rtemax. 281 282* Changes in bgpd 283 284** IPv4 multicast and IPv6 unicast configuration is changed to so 285called new config. All of AFI and SAFI specific configuration is 286moved to "address-family" node. When you have many IPv6 only 287configuration, you will see many "no neighbor X:X::X:X activate" line 288in your configuration to disable IPv4 unicast NLRI exchange. In that 289case please use "no bgp default ipv4-unicast" command to suppress the 290output. Until zebra-0.93, old config is still left for compatibility. 291 292Old config 293========== 294router bgp 7675 295 bgp router-id 10.0.0.1 296 redistribute connected 297 network 192.168.0.0/24 298 neighbor 10.0.0.2 remote-as 7675 299 ipv6 bgp network 3ffe:506::/33 300 ipv6 bgp network 3ffe:1800:e800::/40 301 ipv6 bgp aggregate-address 3ffe:506::/32 302 ipv6 bgp redistribute connected 303 ipv6 bgp neighbor 3ffe:506:1000::2 remote-as 1 304 305New config 306========== 307router bgp 7675 308 bgp router-id 10.0.0.1 309 network 192.168.0.0/24 310 redistribute connected 311 neighbor 10.0.0.2 remote-as 7675 312 neighbor 3ffe:506:1000::2 remote-as 1 313 no neighbor 3ffe:506:1000::2 activate 314! 315 address-family ipv6 316 network 3ffe:506::/33 317 network 3ffe:1800:e800::/40 318 aggregate-address 3ffe:506::/32 319 redistribute connected 320 neighbor 3ffe:506:1000::2 activate 321 exit-address-family 322 323* Changes in ospfd 324 325** Internal interface treatment is changed. Now ospfd can handle 326multiple IP address for an interface. 327 328** Redistribution of loopback interface's address works fine. 329 330* Changes in zebra-0.91 331 332** --enable-oldrib configure option is removed. 333 334** HAVE_IF_PSEUDO part is removed. Same feature is now supported by 335default. 336 337* Changes in ripd 338 339** When redistributed route is withdrawn, perform poisoned reverse. 340 341* Changes in zebra 342 343** When interface's address is removed, kernel route pointing out to 344the address is removed. 345 346** IPv6 RIB is now based upon new RIB code. 347 348** zebra can handle same connected route to one interface. 349 350** New command for interface address. Currently this commands are 351only supported on GNU/Linux with netlink interface. 352 353"ip address A.B.C.D secondary" 354"ip address A.B.C.D label LABEL" 355 356* Changes in bgpd 357 358** BGP flap dampening bugs are fixed. 359 360** BGP non-blocking TCP connection bug is fixed. 361 362** "show ip bgp summary" shows AS path and community entry number. 363 364** New commands have been added. 365 "show ip bgp cidr-only" 366 "show ip bgp ipv4 (unicast|multicast) cidr-only" 367 "show ip bgp A.B.C.D/M longer-prefixes" 368 "show ip bgp ipv4 (unicast|multicast) A.B.C.D/M longer-prefixes" 369 "show ipv6 bgp X:X::X:X/M longer-prefixes" 370 "show ipv6 mbgp X:X::X:X/M longer-prefixes" 371 372** IPv6 IBGP nexthop change is monitored. 373 374** Unknown transitive attribute is passed with partial flag bit on. 375 376* Changes in ospfd 377 378** Fix bug of LSA MaxAge flood. 379 380** Fix bug of NSSA codes. 381 382* Changes in zebra-0.90 383 384** From this beta release, --enable-unixdomain and --enable-newrib 385becomes default. So both options are removed from configure.in. To 386revert old behavior please specify below option. 387 388--enable-tcp-zebra # TCP/IP socket is used for protocol daemon and zebra. 389--enable-oldrib # Turn on old RIB implementation. 390 391Old RIB implementation will be removed in zebra-0.91. 392 393** From this beta release --enable-multipath is supported. This 394option is only effective on GNU/Linux kernel with 395CONFIG_IP_ADVANCED_ROUTER and CONFIG_IP_ROUTE_MULTIPATH is set. 396 397--enable-multipath=ARG # ARG must be digit. When ARG is 0 unlimit multipath number. 398 399** From this release we do not include guile files. 400 401* Changes in lib 402 403** newlist.[ch] is merged with linklist.[ch]. 404 405** Now Zebra works on MacOS X public beta. 406 407** Access-list can have remark. "access-list WORD remark LINE" define 408remark for specified access-list. 409 410** Key of key-chain is sorted by it's idetifier value. 411 412** prefix-list rule is slightly changed. The rule of "len <= ge-value 413<= le-value" is changed to "len < ge-value <= le-value". 414 415** According to above prefix-list rule change, add automatic 416conversion function of an old rule. ex.) 10.0.0.0/8 ge 8 -> 10.0.0.0/8 417le 32 418 419** SMUX can handle SNMP trap. 420 421** In our event library, event thread is executed before any other 422thread like timer, read and write event. 423 424** Robust method for writing configuration file and recover from 425backing up config file. 426 427** Display "end" at the end of configuration. 428 429** Fix memory leak in vtysh_read(). 430 431** Fix memroy leak about access-list and prefix-list name. 432 433* Changes in zebra 434 435** UNIX domain socket server of zebra protocol is added. 436 437** Fix PointoPoint interface network bug. The destination network 438should be installed into routing table instead of local network. 439 440** Metric value is reflected to kernel routing table. 441 442** "show ip route" display uptime of RIP,OSPF,BGP routes. 443 444** New RIB implementation is added. 445 446Now we have enhanced RIB (routing information base) implementation in 447zebra. New RIB has many new features and fixed some bugs which exist 448in old RIB code. 449 450*** Static route with distance value 451 452 Static route can be specified with administrative distance. The 453 distance value 255 means it is not installed into the kernel. 454 Default value of distance for static route is 1. 455 456 ip route A.B.C.D/M A.B.C.D <1-255> 457 ip route A.B.C.D/M IFNAME <1-255> 458 459 If the least distance value's route's nexthop are unreachable, 460 select the least distance value route which has reachable nexthop is 461 selected. 462 463 ip route 0.0.0.0/0 10.0.0.1 464 ip route 0.0.0.0/0 11.0.0.1 2 465 466 In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is 467 reachable. The route with nexthop 11.0.0.1 will be installed into 468 forwarding table. 469 470 zebra> show ip route 471 S>* 0.0.0.0/0 [2/0] via 11.0.0.1 472 S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive 473 474 If the nexthop is unreachable "inactive" is displayed. You can 475 specify any string to IFNAME. There is no need of the interface is 476 there when you configure the route. 477 478 ip route 1.1.1.1/32 ppp0 479 480 When ppp0 comes up, the route is installed properly. 481 482*** Multiple nexthop routes for one prefix 483 484 Multiple nexthop routes can be specified for one prefix. Even the 485 kernel support only one nexthop for one prefix user can configure 486 multiple nexthop. 487 488 When you configure routes like below, prefix 10.0.0.1 has three 489 nexthop. 490 491 ip route 10.0.0.1/32 10.0.0.2 492 ip route 10.0.0.1/32 10.0.0.3 493 ip route 10.0.0.1/32 eth0 494 495 If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0 496 is reachable, then the last route is installed into the kernel. 497 498 zebra> show ip route 499 S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive 500 via 10.0.0.3 inactive 501 * is directly connected, eth0 502 503 '*' means this nexthop is installed into the kernel. 504 505*** Multipath (more than one nexthop for one prefix) can be installed into the kernel. 506 507 When the kernel support multipath, zebra can install multipath 508 routes into the kernel. Before doing that please make it sure that 509 setting --enable-multipath=ARG to configure script. ARG must be digit 510 value. When specify 0 to ARG, there is no limitation of the number 511 of the multipath. Currently only GNU/Linux with netlink interface is 512 supported. 513 514 ip route 10.0.0.1/32 10.0.0.2 515 ip route 10.0.0.1/32 10.0.0.3 516 ip route 10.0.0.1/32 eth0 517 518 zebra> show ip route 519 S>* 10.0.0.1/32 [1/0] via 10.0.0.2 520 * via 10.0.0.3 521 is directly connected, eth0 522 523*** Kernel message delete installed route. 524 525 After zebra install static or dynamic route into the kernel. 526 527 R>* 0.0.0.0/0 [120/3] via 10.0.0.1 528 529 If you delete this route outside zebra, old zebra does not reinstall 530 route again. Now the route is re-processed and properly reinstall the 531 static or dynamic route into the kernel. 532 533** GNU/Linux netlink socket handling is improved to fix race condition 534between kernel message and user command responce. 535 536* Changes in bgpd 537 538** Add show neighbor's routes command. 539 540 "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes" 541 "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes" 542 "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes" 543 "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes" 544 545** BGP passive peer support problem is fixed. 546 547** Redistributed IGP nexthop is passed to BGP nexthop. 548 549** On multiaccess media, if the nexthop is reachable nexthop is passed 550as it is. 551 552** Remove zebra-0.88 compatibility commands. 553 554 "match ip prefix-list WORD" 555 "match ipv6 prefix-list WORD" 556 557 Instead of above please use below commands. 558 559 "match ip address prefix-list WORD" 560 "match ipv6 address prefix-list WORD" 561 562** Fix bug of holdtimer is not reset when bgp cleared. 563 564** "show ip bgp summary" display peer establish/drop count. 565 566** Change "match ip next-hop" argument from IP address to access-list 567name. 568 569** When "bgp enforce-first-as" is enabled, check EBGP peer's update 570has it's AS number in the first AS number in AS sequence. 571 572** New route-map command "set community-delete COMMUNITY-LIST" is 573added. Community matched the CoMMUNITY-LIST is removed from the 574community. 575 576** BGP-MIB implementation is finished. 577 578** When BGP connection comes from unconfigured IP address, close 579socket immediately. 580 581** Do not compare router ID when the routes comes from EBGP peer. 582When originator ID is same, take shorter cluster-list route. If 583cluster-list is same take smaller IP address neighbor's route. 584 585** Add "bgp bestpath as-path ignore" command. When this option is 586set, do not concider AS path length when route selection. 587 588** Add "bgp bestpath compare-routerid".

When interface goes up, restore the routes to the routing 1263table. 1264 1265** `show interface' show interface's statistics on Linux and BSD with 1266routing socket. 1267 1268** Now zebra can get MTU value on BSDI/OS. 1269 1270* Changes in bgpd 1271 1272** Add capability option support based upon 1273draft-ietf-idr-bgp4-cap-neg-04.txt. 1274 1275** Add `show ipv6 bgp prefix-list' command. 1276 1277** Check self AS appeared in received routes. 1278 1279** redistribute route-map support is added. 1280 1281** BGP packet dump feature compatible with MRT. 1282 1283* Changes in ripd 1284 1285** Fix bug of `timers basic' command's argument format. 1286 1287* Changes in ripngd 1288 1289** Calculate max RTE using interface's MTU value. 1290 1291* Changes in ospfd 1292 1293** Some correction to LSU processing. 1294 1295** Add check for lsa->refresh_list. 1296 1297* Changes in ospf6d 1298 1299** Many debug feature is added. 1300 1301* Changes in zebra-0.81 1302 1303** SNMP support is disabled in default.--enable-snmp option is added 1304to configure script. 1305 1306* Changes in bgpd 1307 1308** Fix FSM bug which introduced in zebra-0.80. 1309 1310* Changes in zebra-0.80 1311 1312* access-list 1313 1314 New access-list name space `ipv6 access-list' is added. At the same 1315 time, `access-list' statemant only accepts IPv4 prefix. Please be 1316 careful if you use IPv6 filtering. You will need to change your 1317 configuration. For IPv6 filtering please use `ipv6 access-list'. 1318 1319 As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6 1320 filtering. 1321 1322 ! zebra-0.7x 1323 access-list DML-net permit 203.181.89.0/24 1324 access-list DML-net permit 3ffe:506::0/32 1325 access-list DML-net deny any 1326 ! 1327 1328 Above configuration is not valid for zebra-08x. Please add `ipv6' 1329 before 'access-list' when you configure IPv6 filtering. 1330 1331 ! zebra-0.8x 1332 access-list DML-net permit 203.181.89.0/24 1333 access-list DML-net deny any 1334 ! 1335 ipv6 access-list DML-net permit 3ffe:506::0/32 1336 ipv6 access-list DML-net deny any 1337 ! 1338 1339* prefix-list 1340 1341 And also new prefix-list name space `ipv6 prefix-list' is added. It 1342 is the same as the change of `access-list'. `ip prefix-list' now only 1343 accept IPv4 prefix. It was source of confusion that `ip prefix-list' 1344 can be used both IPv4 and IPv6 filtering. Now name space is separated 1345 to clear the meaning of the filter. 1346 1347 If you use `ip prefix-list' for IPv6 filtering, please change the 1348 stetement. 1349 1350 ! zebra-0.7x 1351 ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24 1352 ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28 1353 ip prefix-list 6bone-filter seq 12 deny 3ffe::/16 1354 ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16 1355 ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35 1356 ip prefix-list 6bone-filter seq 30 deny any 1357 ! 1358 1359 Now user can explicitly configure it as IPv6 prefix-list. 1360 1361 ! zebra-0.8x 1362 ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24 1363 ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28 1364 ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16 1365 ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16 1366 ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35 1367 ipv6 prefix-list 6bone-filter seq 30 deny any 1368 ! 1369 1370* RIP configuration 1371 1372 If you want to filter only default route (0.0.0.0/0) and permit other 1373 routes, it was hard to do that. Now `ip prefix-list' can be used for 1374 RIP route filtering. 1375 1376 New statement: 1377 1378 `distribute-list prefix PLIST_NAME (in|out) IFNAME' 1379 1380 is added to ripd. So you can configure on eth0 interface accept all 1381 routes other than default routes. 1382 1383 ! 1384 router rip 1385 distribute-list prefix filter-default in eth0 1386 ! 1387 ip prefix-list filter-default deny 0.0.0.0/0 le 0 1388 ip prefix-list filter-default permit any 1389 ! 1390 1391* RIPng configuration 1392 1393 Same change is done for ripngd. You can use `ipv6 prefix-list' for 1394 filtering. 1395 1396 ! 1397 router ripng 1398 distribute-list prefix filter-default in eth0 1399 ! 1400 ipv6 prefix-list filter-default deny ::/0 le 0 1401 ipv6 prefix-list filter-default permit any 1402 ! 1403 1404* BGP configuration 1405 1406 So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is 1407 done with traditional IPv4 peering statement like blow. 1408 1409 ! 1410 router bgp 7675 1411 neighbor 3ffe:506::1 remote-as 2500 1412 neighbor 3ffe:506::1 prefix-list 6bone-filter out 1413 ! 1414 1415 For separating configuration IPv4 and IPv6, and for retaining Cisco 1416 configuration compatibility, now IPv6 configuration is done by IPv6 1417 specific statement. IPv6 BGP configuration is done by statement which 1418 start from `ipv6 bgp'. 1419 1420 ! 1421 router bgp 7675 1422 ! 1423 ipv6 bgp neighbor 3ffe:506::1 remote-as 2500 1424 ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out 1425 ! 1426 1427 At the same time some IPv6 specific commands are deleted from IPv4 1428 configuration. 1429 1430 o redistribute ripng 1431 o redistribute ospf6 1432 o neighbor PEER version BGP_VERSION 1433 o neighbor PEER interface IFNAME 1434 1435 Those commands are only accepted as like below. 1436 1437 o ipv6 bgp redistribute ripng 1438 o ipv6 bgp redistribute ospf6 1439 o ipv6 bgp neighbor PEER version BGP_VERSION 1440 o ipv6 bgp neighbor PEER interface IFNAME 1441 1442 And below new commands are added. 1443 1444 o ipv6 bgp network IPV6_PREFIX 1445 o ipv6 bgp redistribute static 1446 o ipv6 bgp redistribute connected 1447 o ipv6 bgp neighbor PEER remote-as <1-65535> [passive] 1448 o ipv6 bgp neighbor PEER ebgp-multihop [TTL] 1449 o ipv6 bgp neighbor PEER description DESCRIPTION 1450 o ipv6 bgp neighbor PEER shutdown 1451 o ipv6 bgp neighbor PEER route-reflector-client 1452 o ipv6 bgp neighbor PEER update-source IFNAME 1453 o ipv6 bgp neighbor PEER next-hop-self 1454 o ipv6 bgp neighbor PEER timers holdtime <0-65535> 1455 o ipv6 bgp neighbor PEER timers keepalive <0-65535> 1456 o ipv6 bgp neighbor PEER send-community 1457 o ipv6 bgp neighbor PEER weight <0-65535> 1458 o ipv6 bgp neighbor PEER default-originate 1459 o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out) 1460 o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out) 1461 o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out) 1462 o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out) 1463 1464 And some utility commands are introduced. 1465 1466 o clear ipv6 bgp [PEER] 1467 o show ipv6 bgp neighbors [PEER] 1468 o show ipv6 bgp summary 1469 1470 I hope these changes are easy to understand for current Zebra users... 1471 1472* To restrict connection to VTY interface. 1473 1474 It used to be both IPv4 and IPv6 filter can be specified with one 1475 access-list. Then the access-list can be appried to VTY interface 1476 with `access-class' stetement in `line vty' node. Below is example in 1477 zebra-0.7x. 1478 1479 ! 1480 access-list local-only permit 127.0.0.1/32 1481 access-list local-only permit ::1/128 1482 access-list local-only deny any 1483 ! 1484 line vty 1485 access-class local-only 1486 ! 1487 1488 Now IPv4 and IPv6 filter have each name space. It is not possible to 1489 specify IPv4 and IPv6 filter with one access-list. For setting IPv6 1490 access-list in `line vty', `ipv6 access-class' statement is 1491 introduced. Let me show the configuration in zebra-0.8x. 1492 1493 ! 1494 access-list local-only permit 127.0.0.1/32 1495 access-list local-only deny any 1496 ! 1497 ipv6 access-list local-only permit ::1/128 1498 ipv6 access-list local-only dny any 1499 ! 1500 line vty 1501 access-class local-only 1502 ipv6 access-class local-only 1503 ! 1504 1505* route-map 1506 1507 New IPv6 related route-map match commands are added. 1508 1509 o match ipv6 address 1510 o match ipv6 next-hop 1511 1512 Please change your configuration if you use IP match statement for 1513 IPv6 route. 1514 1515 zebra-0.7x config 1516 ================= 1517 ! 1518 access-list all permit any 1519 ! 1520 route-map set-nexthop permit 10 1521 match ip address all 1522 set ipv6 next-hop global 3ffe:506::1 1523 set ipv6 next-hop local fe80::cbb5:591a 1524 ! 1525 1526 zebra-0.8x config 1527 ================= 1528 ! 1529 ipv6 access-list all permit any 1530 ! 1531 route-map set-nexthop permit 10 1532 match ipv6 address all 1533 set ipv6 next-hop global 3ffe:506::1 1534 set ipv6 next-hop local fe80::cbb5:591a 1535 ! 1536 1537* zebra connection 1538 1539 Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon 1540 when the connection fail. Those daemons try to connect zebra every 10 1541 seconds first three trial, then the interval changed to 60 seconds. 1542 After all, if ten connections are fail, protocol daemon give up the 1543 connection to the zebra daemon. 1544 1545* SNMP support (is not yet finished) 1546 1547 Zebra uses SMUX protocol (RFC1227) for making communication with SNMP 1548 agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1 1549 and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be 1550 compiled with ucd-snmp-3.6.2. 1551 1552 After applying the patch to ucd-snmp-4.0.1, please configure it with 1553 SMUX module. 1554 1555 % configure --with-mib-modules=smux 1556 1557 After compile & install ucd-snmp-4.0.1, you will need to configure 1558 smuxpeer. I'm now using below configuration. 1559 1560 /usr/local/share/snmp/snmpd.conf 1561 ================================ 1562 smuxpeer 1.3.6.1.6.3.1 test 1563 1564 Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard 1565 coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP. 1566 1567* HUP signal treatment 1568 1569 From zebra-0.80, ripd will reload it's configuration file when ripd 1570 receives HUP signal. Other daemon such as bgpd, ospfd will support 1571 HUP signal treatment soon. 1572 1573* Changes in zebra-0.79 1574 1575* Changes in zebra 1576 1577** Broadcast address setting on Linux box bug is fixed. 1578 1579** Protocol daemon can install connected IPv6 route into the kernel. 1580 1581** Now zebra can handle blackhole route. 1582 1583* Changes in ripd 1584 1585** Add route-map feature for RIP protocol. 1586 1587** In case of RIP version 2 routing table entry has IPv4 address and 1588netmask pair which host part bit is on, ignore the entry. 1589 1590* Changes in ripngd 1591 1592** Change CMSG_DATA cast from (u_char *) to (int *). (u_char *) does 1593not work for NetBSD-currnet on SparcStation 10. 1594 1595* Changes in ospfd 1596 1597** MaxAge LSA treatment is added. 1598 1599** ABR/ASBR functionality is added. 1600 1601** Virtual Link funtionality is added. 1602 1603** ABR behaviors IBM/Cisco/Shortcut is added. 1604 1605* Changes in ospf6d 1606 1607** Enclosed KAME specific part with #ifdef #endif 1608 1609* Changes in zebra-0.78 1610 1611* Changes in lib 1612 1613** SNMP support is started. 1614 1615** Now Zebra can work on BSD/OS 4.X. 1616 1617** Now Zebra can compiled on vanilla OpenBSD 2.5 but not yet working correcltly. 1618 1619* Changes in zebra 1620 1621** Interface index detection using ioctl() bug is fixed. 1622 1623** Interface information protocol is changed.
