Configuration procedure
1.
Create VLANs and assign corresponding ports to them. Configure the IP address of each VLAN
interface as shown in
2.
On Switch A, configure the source address of BFD echo packets as 10.10.10.10.
<SwitchA> system-view
[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.

[SwitchA-Vlan-interface2] vrrp vrid 1 track 1 reduced 20
[SwitchA-Vlan-interface2] return
5.
On Switch B, create VRRP group 1, and configure the virtual IP address of the group as
192.168.0.10.
