# Monitoring VRRP

You can use several VRRP show commands to display the details of your VRRP configuration.

baseline ip vrrp

- Use to establish the baseline on all VRRP statistics as the current value.
- Example
  `
  host1#baseline ip vrrp
  `

- See show ip vrrp.

show ip vrrp neighbor

- Use to display neighbors currently known to the VRRP routers.
- A neighbor—a router that shares a given VRID with the VRRP router—is known to the VRRP router only when the neighbor becomes a master for an IP address and sends VRRP advertisements to that effect. If a router sharing the VRID has not yet become a master, then the local router remains unaware of this neighbor and this command does not display that neighbor.
- Use the interface keyword to specify a specific Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface.
- Field descriptions
  - Interface—Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface specifier and VRID of neighbors known to the VRRP router
  - time discovered—Date and time that the neighbor was detected
  - primary address—Primary IP address of neighbor
  - adv interval (sec)—VRRP advertisement interval in seconds
  - priority—Priority status of VRRP router (255 = owner)
  - auth type—VRRP authentication type: none or text
  - assoc address(es)—IP addresses associated with the VRID that are advertised by the neighbor
- Example

      host1#show ip vrrp neighbor
      Interface: fastEthernet5/0.0 vrrpVrid: 1
        time discovered: 08/09/2001 07:44
