VRRP Statistics

Virtual Router Redundancy Protocol (VRRP) support on the GbE Switch Module 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 statistics for the VRRP LAN are displayed:

VRRP statistics:	0	vrrpBadAdvers:	0

vrrpOutAdvers:	0	vrrpBadVrid:	0
vrrpBadVersion:	0
