change the status of Switch B to master. The backup can quickly preempt as the master without
waiting for a period three times the advertisement interval plus the Skew_Time.
Configuring BFD for the VRRP master to monitor the uplinks
Network requirements
As shown in Figure 46:
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 uplink on the master and meet the following
requirements:
When Switch A operates correctly, the hosts in the LAN access the Internet through Switch A.
When Switch A detects that the uplink is down through BFD, Switch B can preempt as the
master. The hosts in the LAN can access the Internet through Switch B.
