VRRP example

To implement the VRRP configuration shown in
commands.
Configuring Router1
To configure VRRP Router1, enter the following commands.
Router1(config)# router vrrp
Router1(config)# inter e 1/6
Router1(config-if-e10000-1/6)# ip address 192.53.5.1
Router1(config-if-e10000-1/6)# ip vrrp vrid 1
Router1(config-if-e10000-1/6-vrid-1)# owner track-priority 20
Router1(config-if-e10000-1/6-vrid-1)# track-port ethernet 2/4
Router1(config-if-e10000-1/6-vrid-1)# ip-address 192.53.5.1
Router1(config-if-e10000-1/6-vrid-1)# activate
NOTE
When you configure the Master (Owner), the address you enter with the ip-address command must
already be configured on the interface.
The ip vrrp owner command specifies that this router owns the IP address you are associating with
the virtual router. Because this router owns the IP address, this router is the default Master router
and its VRRP priority is thus 255.
Configuring Router2
To configure Router2 in
Router2(config)# router vrrp
Router2(config)# inter e 1/5
Router2(config-if-e10000-1/5)# ip address 192.53.5.3
Router2(config-if-e10000-1/5)# ip vrrp vrid 1
Router2(config-if-e10000-1/5-vrid-1)# backup priority 100 track-priority 19
Router2(config-if-e10000-1/5-vrid-1)# track-port ethernet 3/2
Router2(config-if-e10000-1/5-vrid-1)# ip-address 192.53.5.1
Router2(config-if-e10000-1/5-vrid-1)# activate
The backup command specifies that this router is a VRRP Backup for virtual router VRID1. The IP
address entered with the ip-address command is the same IP address as the one entered when
configuring Router1. In this case, the IP address cannot also exist on Router2, but the interface on
which you are configuring the virtual router Backup must have an IP address in the same subnet.
By entering the same IP address as the one associated with this virtual router on the Owner, you
are configuring the Backup to back up the address, but you are not duplicating the address.
NOTE
When you configure a Backup router, the router interface on which you are configuring the virtual
router must have a real IP address that is in the same subnet as the address associated with the
virtual router by the Owner. However, the address cannot be the same.
The priority parameter establishes the router's VRRP priority in relation to the other VRRP routers in
this virtual router. The track-priority parameter specifies the new VRRP priority that the router
receives for this virtual router if the interface goes down. Refer to
page 442.
