Router A and Router B belong to VRRP group 1. The virtual IP address of VRRP group 1 is
•
192.168.0.10.
The default gateway of the hosts in the LAN is 192.168.0.10.
•
Configure VRRP-Track-BFD collaboration to monitor the uplink on the master and meet the following
requirements:
When Router A operates correctly, hosts in the LAN access the Internet through Router A.
•
