Configuration procedure
1. Create VLANs and assign corresponding ports to them. Configure the IP address of each VLAN
interface as shown in
Figure 23 . (Details not shown.)
2. On Switch A, configure the source address of BFD echo packets as 10.10.10.10.

[SwitchA] bfd echo-source-ip 10.10.10.10
3. 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.
[SwitchA] track 1 bfd echo interface vlan-interface 3 remote ip 1.1.1.2 local ip
1.1.1.1
4. On Switch A, create VRRP group 1, and configure the virtual IP address of the group as
192.168.0.10. Configure the priority of Switch A in VRRP group 1 as 110. Configure VRRP group
1 to monitor the status of track entry 1. When the status of the track entry becomes Negative, the
priority of Switch A decreases by 20.

5. On Switch B, create VRRP group 1, and configure the virtual IP address of the group as
192.168.0.10.
