VRRP Information
Virtual Router Redundancy Protocol (VRRP) support on GbE Switch Module provides redun-
dancy 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 view the status of each virtual router using this
command. VRRP information includes:
Virtual router number
Virtual router ID and IP address
Interface number
Ownership status
owner identifies the preferred master virtual router. A virtual router is the owner
when the IP address of the virtual router and its IP interface are the same.
renter identifies virtual routers which are not owned by this device.
Priority value. During the election process, the virtual router with the highest priority
becomes master.
Activity status
master identifies the elected master virtual router.
backup identifies that the virtual router is in backup mode.
init identifies that the virtual router is waiting for a startup event.
For example, once it receives a startup event, it transitions to master if its priority
is 255, (the IP address owner), or transitions to backup if it is not the IP address
owner.
Server status. The server state identifies virtual routers.
Proxy status. The proxy state identifies virtual proxy routers, where the virtual router
shares the same IP address as a proxy IP address. The use of virtual proxy routers enables
redundant switches to share the same IP address, minimizing the number of unique IP
addresses that must be configured.
