.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility manipulates the address mapping table
|
|
used by Neighbor Discovery Protocol (NDP).
|
|
.Bl -tag -width Ds
|
|
.It Fl a
|
|
Dump the currently existing NDP entries.
|
|
.It Fl A Ar wait
|
|
Repeat
|
|
.Fl a
|
|
(dump NDP entries)
|
|
every
|
|
.Ar wait
|
|
seconds.
|
|
.It Fl c
|
|
Erase all the NDP entries.
|
|
.It Fl d
|
|
Delete specified NDP entry.
|
|
.It Fl f
|
|
Parse the file specified by
|
|
.Ar filename .
|
|
.It 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.
|
|
.It Fl I Op Cm delete | Ar interface
|
|
Shows or specifies the default interface used as the default route when
|
|
there is no default router.
|
|
If no argument is given to the option,
|
|
the current default interface will be shown.
|
|
If an
|
|
.Ar interface
|
|
is specified, the interface will be used as the default.
|
|
If a special keyword
|
|
.Ic delete
|
|
is specified, the current default interface will be deleted from the kernel.
|
|
.It Fl i Ar interface Op Ar flags...
|
|
View ND information for the specified interface.
|
|
If additional arguments
|
|
.Ar flags
|
|
are given,
|
|
.Nm
|
|
sets or clears the specified flags for the interface.
|
|
Possible flags are as follows.
|
|
All of the flags can begin with the
|
|
special character
|
|
.Ql - ,
|
|
which means the flag should be cleared.

|
|
turn on or off NUD (Neighbor Unreachability Detection) on the
|
|
interface.
|
|
NUD is usually turned on by default.
|
|
.El
|
|
.It Fl n
|
|
Do not try to resolve numeric address to hostname.
|
|
.It Fl p

Flush all the entries in the prefix list.
|
|
.It Fl r
|
|
Show default router list.
|
|
.It Fl R
|
|
Flush all the entries in the default router list.
|
|
.It Fl s
|

The entry will be permanent unless the word
|
|
.Li temp
|
|
is given in the command.
|

If the word
|
|
.Li proxy
|
|
is given, this system will act as a proxy NDP server,

|
.Ar hostname
|
|
even though the host address is not its own.
|
|
.It Fl t
|
|
Print timestamp on each entries,
|
|
to make it possible to merge output with
