Figure 162 VRRP Example 1: VRRP Status on Switch B

34.4.2 Two Subnets Example

The following figure depicts an example in which two switches share the network traffic. Hosts in the two network groups use different default gateways. Each switch is configured to backup a virtual router using VRRP.

You wish to configure switch A as the master router for virtual router VR1 and as a backup for virtual router VR2. On the other hand, switch B is the master for VR2 and a backup for VR1.

Keeping the VRRP configuration in example 1 for virtual router VR1 (refer to Section 34.4.2 on page 278), you need to configure the VRRP Configuration screen for virtual router VR2 on each switch. Configure the VRRP parameters on the switches as shown in the figures below.
