Summary

Sub-menu: /ipv6 neighbor
Standards: RFC 4861
Package : IPv6


List of all discovered nodes by IPv6 neighbor discovery protocol (neighbor cache).

Property Description
address (ipv6 address) link-local address of the node.
comment (string)
inteface (string) Interface on which node was detected.
mac-address (string) Mac address of discovered node.
router (yes | no) Whether discovered node is router
status (noarp | incomplete | stale | reachable | delay | probe) Status of the cached entry:
  • noarp -
  • incomplete - address resolution is in progress and the link-layer address of the neighbor has not yet been determined;
  • reachable - the neighbor is known to have been reachable recently (within tens of seconds ago);
  • stale - the neighbor is no longer known to be reachable but until traffic is sent to the neighbor, no attempt should be made to verify its reachability;
  • delay - the neighbor is no longer known to be reachable, and traffic has recently been sent to the neighbor, probes are delayed for a short period in order to give upper layer protocol a chance to provide reachability confirmation;
  • probe - the neighbor is no longer known to be reachable, and unicast Neighbor Solicitation probes are being sent to verify reachability.
