DESCRIPTION

The ndp command manipulates the address mapping table used by Neighbor Discovery Protocol (NDP).

OPTIONS

-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.
