Configuring parameters specific to VRRP

Configuring basic VRRP parameters
To implement a simple VRRP configuration using all the default values, enter commands such as
the following.
Configuring the owner
Router1(config)# router vrrp
Router1(config)# interface ethernet 1/6
Router1(config-if-e10000-1/6)# ip default-network 192.53.5.1
Router1(config-if-e10000-1/6)# ip vrrp vrid 1
Router1(config-if-e10000-1/6-vrid-1)# owner
Router1(config-if-e10000-1/6-vrid-1)# ip-address 192.53.5.1
Router1(config-if-e10000-1/6-vrid-1)# activate
Configuring a backup
To configure the VRRP Backup router, enter the following commands.
Router2(config)# router vrrp
Router2(config)# interface ethernet 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
Router2(config-if-e10000-1/5-vrid-1)# advertise backup
Router2(config-if-e10000-1/5-vrid-1)# ip-address 192.53.5.1
Router2(config-if-e10000-1/5-vrid-1)# activate
When you configure a Backup router, the router interface on which you are configuring the VRID
must have a real IP address that is in the same subnet as the address associated with the VRID by
the Owner. However, the address cannot be the same.
Syntax: router vrrp
Syntax: backup [priority <value>] [track-priority <value>]
The priority <value> parameter specifies the VRRP priority for this virtual router. You can specify a
value from 3 – 254. The default is 100.
Enter a value of 3 – 254 for the track-priority <value> parameter if you want VRRP to monitor the
state of the interface. The default is 100.
Syntax: ip-address <ip-addr>
Refer to “Configuration rules for VRRP” on page 465 for additional requirements.
Configuration rules for VRRP
• The interfaces of all routers in a virtual router must be in the same IP subnet.
• The IP address(es) associated with the virtual router must already be configured on the router
that will be the Owner router.
• The IP address for the virtual router must be on only one router.
• The Hello interval must be set to the same value on both the Owner and Backups for the virtual
router.
