Configuring BFD for the VRRP master to monitor the uplinks Network requirements • As shown in Figure 29, Switch A and Switch B belong to VRRP group 1, whose virtual IP address is 192.168.0.10. • The default gateway of the hosts in the LAN is 192.168.0.10. • When Switch A operates correctly, the hosts in the LAN access the external network through Switch A. When Switch A detects that the uplink is down through BFD, it decreases its priority so that Switch B can preempt as the master, ensuring that the hosts in the LAN can access the external network through Switch B.

Create VLANs and assign corresponding ports to them. Configure the IP address of each VLAN interface as shown in Figure 29. (Details not shown.) 2. Configure BFD on Switch A: # Configure the source address of BFD echo packets as 10.10.10.10. system-view [SwitchA] bfd echo-source-ip 10.10.10.10 3. Create a track entry to be associated with the BFD session on Switch A: # Create track entry 1 to be associated with the BFD session to check whether the uplink device with the IP address 1.1.1.2 is reachable.
