Procedure
Step 1 Configure VRRP.
# On Router A, configure the IP address of the interface, create backup group 1 and configure
the priority of Router A in this group with 120 (as the master router).
Issue 01 (2012-01-06)
Router A and Router B form a VRRP backup group that serves as the default gateway for
Host A.
Normally, Router A serves as the gateway. When Router A fails, Router B serves as the
gateway.
Router A continues to function as the master router within 20 seconds after it recovers.

Create the backup group 1 on the GE 2/0/0 on Router A and configure Router A with the
highest priority in the backup group to be the master router. Configure the preemption
mode.
Create backup group 1 on the GE 2/0/0 interface on Router B and use the default priority.
