VRRP statistics
Virtual Router Redundancy Protocol (VRRP) support on this switch provides redundancy between routers in a LAN.
This is accomplished by configuring the same virtual router IP address and ID number on each participating VRRP-
capable routing device.
One of the virtual routers is then elected as the master, based on a number of priority criteria, and assumes control
of the shared virtual router IP address. If the master fails, one of the backup virtual routers will assume routing
authority and take control of the virtual router IP address.
When virtual routers are configured, you can display the following protocol statistics for VRRP:
Advertisements received (
vrrpInAdvers
)
Advertisements transmitted (
vrrpOutAdvers
)
Advertisements received, but ignored (
vrrpBadAdvers
)
The following command displays statistics for the VRRP LAN:
