NAME
     ndp -- control/diagnose IPv6 neighbor discovery protocol

SYNOPSIS
     ndp -a [-nt]
     ndp -A wait [-nt]
     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]

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

     -a      Dump the currently existing NDP entries.

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

     -c      Erase all the NDP entries.

     -d      Delete specified NDP entry.

     -f      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]
	     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 inter-
	     face 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...]
	     View 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     turn on or off NUD (Neighbor Unreachability Detection) on the interface.
		     NUD is usually turned on by default.

     -n      Do not try to resolve numeric address to hostname.

     -p      Show prefix list.

     -P      Flush all the entries in the prefix list.

     -r      Show default router list.

     -R      Flush all the entries in the default router list.

     -s      Register an 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      Print timestamp on each entries, to make it possible to merge output with
	     tcpdump(1).  Most useful when used with -A.

RETURN VALUES
     The ndp command will exit with 0 on success, and non-zero on errors.

HISTORY
     The ndp command first appeared in WIDE Hydrangea IPv6 protocol stack kit.
