The ndp command manipulates the address mapping table used
by Neighbor Discovery Protocol (NDP).
- -a
- Dumps the currently existing NDP entries.
- -A
- wait Repeats -a (dump NDP entries) every wait
seconds
- -c
- Erases all the NDP entries.
- -d
- Deletes specified NDP entry.
- -f
- Parses the file specified by filename.
- -H
- Harmonizes consistency between the routing table
and the default router list; install the top entry
of the list into the kernel routing table.
- -I
- [ delete | 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 interface is specified, the
interface will be used as the default. If a
special keyword delete is specified, the current
default interface will be deleted from the kernel.
- -i
- interface [ flags... ] Views ND information for
the specified interface. If additional arguments
flags are given, ndp sets or clears the specified
flags for the interface. Possible flags are as
follows. All of the flags can begin with the
special character `-' which means the flag should
be cleared.
- nud
- Turns on or off NUD (Neighbor Unreachability
Detection) on the interface. NUD is usually
turned on by default.
- -l
- Does not truncate numeric IPv6 address.
- -n
- Does not try to resolve numeric address to
hostname.
- -p
- Shows prefix list.
- -P
- Flushes all the entries in the prefix list.
- -r
- Shows default router list.
- -R
- Flushes all the entries in the default router list.
- -s
- Registers a NDP entry for a node. The entry will
be permanent unless the word temp is given in the
command. If the word proxy is given, this system
will act as an proxy NDP server, responding to
requests for hostname even though the host address
is not its own.
- -t
- Prints timestamp on each entry, to make it possible
to merge output with pktt. Most useful when used
with -A.
