Configuration procedure
1.
Create VLANs and assign corresponding ports to them. Configure the IP address of each VLAN
interface as shown in
2.
Configure VRRP on Switch A:
<SwitchA> system-view
[SwitchA] interface vlan-interface 2
# Create VRRP group 1, and configure the virtual IP address 192.168.0.10 for the group. Set the
priority of Switch A in VRRP group 1 to 110.
[SwitchA-Vlan-interface2] vrrp vrid 1 virtual-ip 192.168.0.10
[SwitchA-Vlan-interface2] vrrp vrid 1 priority 110
[SwitchA-Vlan-interface2] return
3.
On Switch B, configure the source address of BFD echo packets as 10.10.10.10.
<SwitchB> system-view
[SwitchB] bfd echo-source-ip 10.10.10.10
4.
On Switch B, create track entry 1 to be associated with the BFD session to check whether Switch
A is reachable.
[SwitchB] track 1 bfd echo interface vlan-interface 2 remote ip 192.168.0.101 local
ip 192.168.0.102
5.
On Switch B, create VRRP group 1, and configure the virtual IP address 192.168.0.10 for the
group. VRRP group 1 monitors the status of track entry 1. When the status of the track entry
becomes Negative, Switch B quickly becomes the master.
