Monitoring the Configuration of VRRP Neighbors

Purpose

Display neighbor information to the VRRP routers. Neighbor is a router that shares a given VRID with the VRRP router. A neighbor is known to the VRRP router only when the neighbor becomes a master for an IP address and sends VRRP advertisements. If a router sharing the VRID has not yet become a master router, then the local router remains unaware of this neighbor and this command does not display that neighbor.

Action

To display information about all known neighbors to the VRRP routers: 

host1#show ip vrrp neighbor
Interface: fastEthernet5/0.0 vrrpVrid: 1
  time discovered: 08/09/2001 07:44
  primary address: 10.0.0.1
  adv interval (sec): 1
  priority: 255 (owner)
  auth type: none
  assoc address(es): 10.0.0.1, 100.0.0.1, 101.0.0.1
Interface: fastEthernet5/0.1 vrrpVrid: 11
  time discovered: 08/09/2001 07:44
  primary address: 11.0.0.1
  adv interval (sec): 1
  priority: 255 (owner)
  auth type: none
  assoc address(es): 11.0.0.1, 110.0.0.1, 111.0.0.1
