    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
