ndp(1Mtcp)
ndp --
control and display operation of NDP
Synopsis
ndp [-n] hostname
ndp [-n] -a
ndp [-d] hostname
ndp [-i interface_index] -s hostname address [temp]
Description
The ndp program displays and modifies the
IPv6-to-hardware address translation
tables used by the IPv6
neighbor discovery protocol (NDP).
(ndp performs an analogous function to that of the
arp(1Mtcp)
command in IPv4.)
If no options are specified,
ndp displays the current entry for hostname. The
host may be specified by name or IPv6 address.
ndp understands the following options:
-a-
Display all current NDP table entries.
-d-
Delete an entry from the NDP table.
-i interface_index-
Specify the index of the interface to use when an NDP table entry
is added with the -s flag (useful with local-link interfaces).
-n-
Display numerical network addresses as numbers instead of
attempting to resolve them into domain names. This greatly speeds up
the performance of the ndp command.
-s hostname address [temp]-
Create an NDP entry for hostname with the
specified hardware address. The address must be entered as six
colon-separated hexadecimal bytes.
The entry is permanent unless the keyword temp is specified.

Examples
List the entries in the NDP table:
ndp -a
This command produces output such as:
e-crankv6 (::903:9182) at link#2 0:20:af:db:b8:cf
e-crankv6-11 (fe80::100:0:0220:afff:fedb:b8cf) at link#2 0:20:af:db:b8:cf
Delete the entry for e-crankv6-11:
ndp -d e-crankv6-11
This command produces output such as:
e-crankv6-11 (fe80::100:0:0220:afff:fedb:b8cf) deleted
