Configuration examples
The following sections contain the CLI commands for implementing VRRP and VRRP-E configurations.

VRRP example

To implement the VRRP configuration shown in "VRRP Overview," use the following method.
Configuring Switch 1
To configure VRRP Switch 1, enter the following commands.
Switch1(config)# router vrrp
Switch1(config)# interface ethernet 1/1/6
Switch1(config-if-1/1/6)# ip address 192.53.5.1
Switch1(config-if-1/1/6)# ip vrrp vrid 1
Switch1(config-if-1/1/6-vrid-1)# owner track-priority 20
Switch1(config-if-1/1/6-vrid-1)# track-port ethernet 1/2/4
Switch1(config-if-1/1/6-vrid-1)# ip-address 192.53.5.1
Switch1(config-if-1/1/6-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.
Configuring Switch 2
To configure Switch 2 in "VRRP Overview" after enabling VRRP, enter the following commands.
Switch2(config)#router vrrp
Switch2(config)#interface ethernet 1/1/5
Switch2(config-if-1/1/5)#ip address 192.53.5.3
Switch2(config-if-1/1/5)#ip vrrp vrid 1
Switch2(config-if-1/1/5-vrid-1)#backup priority 100 track-priority 19
Switch2(config-if-1/1/5-vrid-1)#track-port ethernet 1/3/2
Switch2(config-if-1/1/5-vrid-1)#ip-address 192.53.5.1
Switch2(config-if-1/1/5-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 Switch 1. In this case, the IP address cannot also exist on Switch
2, but the interface on which you are configuring the VRID Backup must have an IP address in the same subnet. By entering the same IP
address as the one associated with this VRID 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 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.
The priority parameter establishes the router 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 VRID if the interface goes down.
The activate command activates the VRID configuration on this interface. The interface does not provide backup service for the virtual IP
address until you activate the VRRP configuration. Alternatively, you can use the enable command. The activate and enable commands
do the same thing.
