00-00-5E-00-01-<VRID>

Where the VRID is an integer value in the range 1 to 255 that represents the virtual router identiﬁcation.

The virtual MAC address is assigned when VRRP is conﬁgured on a switch port or VLAN. The following example represents this process:

5530-24TFD# config terminal

5530-24TFD(config)# interface vlan 2

5530-24TFD(config-if)# ip vrrp address 199 10.1.20.1 5530-24TFD(config-if)# ip vrrp 199 enable

Conﬁguring normal VRRP operation

The following conﬁguration example (illustrated below) shows how to provide VRRP service for two edge host locations.

VRRP example topology

In this example, the switches have the following duties:

•R1 is the VRRP master for S2

•R2 is the VRRP master for S1

In this example, VRRP is enabled with OSPF as the routing protocol on R1 and R2.
