VRRP information

Virtual Router Redundancy Protocol (VRRP) support on HP 1:10GbE 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.
The following command displays VRRP information:
show ip vrrp information
Command mode: All except User EXEC
VRRP information:
1: vrid 2, 205.178.18.210, if 1, renter, prio 100, master, server
2: vrid 1, 205.178.18.202, if 1, renter, prio 100, backup
3: vrid 3, 205.178.18.204, if 1, renter, prio 100, master, proxy
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. 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.
