    Configuring VRRP Instances to Match ICR Requirements

    Each ICR partition is managed by a unique VRRP instance. You can specify an ICR partition as the master partition by assigning a higher priority. Use the ip vrrp priority command to assign priorities to the ICR partitions.

    To configure the VRRP instance to match ICR requirements:

    1. Create a VRRP instance by specifying the identification number, and associate an IP address with the identification number.
      host1(config-if)#ip vrrp 1 virtual-address 3.5.1.10
    2. Specify the priority of the router. Assign the higher priority to the master ICR partition and a lower priority to the backup ICR partition.
      host1(config-if)#ip vrrp priority 200
    3. (Optional) Enable the router to learn the VRRP advertisement interval. Use this only when you plan on upgrading your router by means of a unified in-service software upgrade (ISSU).
      host1(config-if)#ip vrrp 1 timers-learn
    4. Enable the VRRP instance.
      host1(config-if)#ip vrrp 1 enable
    5. (Optional) Configure additional VRRP instances by completing Steps 1 through 4, using unique numbering.
