Data Preparation
To complete the configuration, you must prepare the following data:
Issue 01 (2012-01-06)
RouterA and RouterB constitute a VRRP group to function as the default gateway of Host.
RouterA functions as the gateway. When RouterA fails, RouterB becomes the gateway.
After RouterA recovers, it preempts to be the master within 20 seconds.
User packets sent from Switch carry one tag.
Configure VRRP on the Dot1q termination subinterface GE2/0/0.1 on RouterA and
RouterB.

Configure OSPF to enable RouterA, RouterB, and RouterC to communicate with each
other.
Configure Dot1q termination subinterfaces on RouterA and RouterB.
Create backup group 1 on GE2/0/0.1 of RouterA. Configure the highest priority for
RouterA in the backup group to ensure that RouterA functions as the master. Configure the
preemption mode for RouterA.
Create backup group 1 on GE2/0/0.1 of RouterB and use the default priority.
Configure the basic Layer 2 forwarding function on Switch.
