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 rout- ing 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...] 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. SEE ALSO
arp(8) HISTORY
The ndp command first appeared in WIDE Hydrangea IPv6 protocol stack kit. BSD
May 17, 1998 BSD

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. disabled IPv6 can be disabled separately from other network protocols. This flag can be turned on automatically when Duplicate Address Detection (DAD) indicates that another device on the network is using the same link-local address. proxy_prefixes the interface is enabled to proxy neighbor discovery for global scope prefixes matching those on link at other interfaces. insecure do not use cryptographically generated addresses (CGA) on this interface. replicated Address autoconfiguration proceeds under the assumption that interface configuration is replicated by a sleep proxy at another node on the link. Disables optimistic DAD and sends unsolicited NA with O=1 when DAD completes. Ignores DAD failures from other hardware addresses. -l Show link-layer reachability information. -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. -x Show extended link-layer reachability information in addition to that shown by the -l flag. -w Show the cryptographically generated address (CGA) parameters for the node.
