intervals.
Configuration Examples
The following sections contain the CLI commands for implementing the VRRP and VRRPE configurations shown
in Figure 22.2 on page 22-3 and Figure 22.3 on page 22-7.
VRRP Example
To implement the VRRP configuration shown in Figure 22.2 on page 22-3, use the following method.
Configuring Router1
To configure VRRP Router1, enter the following commands:
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 VRID.
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 Figure 22.2 on page 22-3 after enabling VRRP, enter the following commands:
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 VRID
Backup must have an IP address in the same sub-net. 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 sub-net as the address associated with the VRID by the Owner.
However, the address cannot be the same.
Router1(config)# router vrrp

Router1(config-if-1/6)# ip address 192.53.5.1

Router2(config-if-1/5)# ip address 192.53.5.3
Router2(config-if-1/5)# ip vrrp vrid 1
Router2(config-if-1/5-vrid-1)# backup priority 100 track-priority 19
Router2(config-if-1/5-vrid-1)# track-port ethernet 3/2
Router2(config-if-1/5-vrid-1)# ip-address 192.53.5.1
Router2(config-if-1/5-vrid-1)# activate
