Creating VRIDs

A master or backup router running the VRRP protocol can participate in one or more VRID instances. You can create a VRID instance in several ways:

• We recommend that you create and configure a VRID instance first, and enable it last. For example:

  host1(config-if)#ip vrrp 198

  host1(config-if)#ip vrrp 198 priority 255

• You can create and enable a VRID instance by using the ip vrrp vrid enable command. For example:

  host1(config-if)#ip vrrp 25 enable

• You continue to configure the VRID by identifying the VRID each time you use a VRRP command. For example:

  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
