`ndp`

Control the IPv6 Neighbor Discovery Protocol

Syntax:

ndp -A wait [-ntl]
ndp -a [-ntl]
ndp -c [-nt]
ndp -d [-nt] hostname
ndp -f [-nt] filename
ndp -H
ndp -I [delete|interface]
ndp -i interface [flags...]
ndp -P
ndp -p
ndp -R
ndp -r
ndp -s [-nt] nodename ether_addr [temp] [proxy]

Runs on:

Neutrino

Options:

-A wait

Repeat -a (dump NDP entries) every wait seconds.

-a

Dump the existing NDP entries.

-c

Erase all NDP entries.

-d hostname

Delete the NDP entry for this hostname.

-f filename

Parse the file specified by filename.

-H

Harmonize 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]

Show or specify the default interface that's to be used as the default route when there's no default router.

Option:	Action:
`-I`	Show the current default interface.
`-I delete`	Delete the current interface from the kernel.
`-I` interface	Use this interface as the default.

-i interface [flags...]

View the neighbor discovery (ND) information for this interface. If flags is specified, set or clear the flag(s) associated with this interface. A flag is cleared if it starts with the special character “-”. Possible flags are:

nud: Toggle NUD (Neighbor Unreachability Detection) on the interface (default is on).

-l

Don't truncate the numeric IPv6 addresses.

-n

Don't try to resolve a numeric address to a hostname.

-P

Flush all the entries in the prefix list.

-p

Show the prefix list.

-R

Flush all the entries in the default router list.

-r

Show the default router list.

-s nodename ether_addr [temp] [proxy]

Register a permanent NDP entry for this node (use temp to register a temporary entry). If you specify proxy, the system acts as a proxy NDP server that responds to requests for hostname even though the host address is not its own.

-t

Print a timestamp on each entry so that it's possible to merge the output with tcpdump. Typically used with -A.

Description:

This utility manipulates the address mapping table used by the Neighbor Discovery Protocol (NDP).

Exit status:

0: Successful completion.
Nonzero: An error occurred.
