Configuration Steps

Before you configure VRRP, we recommend that you review the configuration
examples in the earlier section "How VRRP Works" on page 107.
To configure VRRP parameters:
1.
2.
3.
4.
5.
6.
host1(config-if)#ip vrrp 175 authentication-type none
Alternatively, you can create a new VRID when you use any VRRP command,
provided that you are using the VRID instance for the first time. For example, if
you execute the ip vrrp vrid preempt command and it is the first time that you
use the VRID, the command creates a new VRID.
host1(config-if)#ip vrrp 16 preempt
Use the ip vrrp vrid enable command last. The new VRID is not enabled until
you execute this command.
host1(config-if)#ip vrrp 198 enable
host1(config-if)#ip vrrp 16 enable
host1(config-if)#ip vrrp 175 enable
(Optional) Create a VRID instance.
host1(config-if)#ip vrrp 25
(Optional) Set a VRRP advertisement interval for the same VRID.
host1(config-if)#ip vrrp 25 advertise-interval 50
Set the VRRP router priority for owner or backup routers.
This step is mandatory to configure priority for the owner VRID (255). This step
is optional to configure priority for a backup VRID (1–254). The default value is
100.
host1(config-if)#ip vrrp 25 priority 255
host1(config-if)#ip vrrp 22 priority 254
(Optional) Specify that the backup router can process packets with an IP
destination address of the virtual address.
host1(config-if)#ip vrrp 22 accept-data
(Optional) Set the preempt option. This example creates a new VRID.
host1(config-if)#ip vrrp 10 preempt
Associate an IP address with a VRID.
host1(config-if)#ip vrrp 25 virtual-address 194.2.1.63
