Network requirements
As shown in Figure 34:
Switch A and Switch 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 master on the backup and meet the following
requirements:
When Switch A operates correctly, the hosts in the LAN access the Internet through Switch A.
When Switch A fails, the backup (Switch B) can detect the state change of the master through BFD
and become the new master. The hosts in the LAN access the Internet through Switch B.
