.Sh DESCRIPTION .Nm command manipulates the address mapping table used by Neighbor Discovery Protocol (NDP). l -tag -width Ds t Fl a Dump the currently existing NDP entries. t Fl A Ar wait Repeat .Fl a
q dump NDP entries
every
.Ar wait
seconds.
t Fl c Erase all the NDP entries.
t Fl d Delete specified NDP entry.
t Fl f Parse the file specified by
.Ar filename .
t Fl H Harmonize consistency between the routing table and the default router
list; install the top entry of the list into the kernel routing table.
t Fl i view ND information for specified interface.

t Fl r Show default router list.
t Fl R Flush all the entries in the default router list.
t Fl s Register a NDP entry for a node.
t Fl t Print timestamp on each entries,
to make it possible to merge output with
.Xr tcpdump 1 .
Most useful when used with
