Step 2

Set IP addresses of VLANIF 13 interfaces so that Switch A can communicate with Switch B at
Layer 3.

# Configure Switch A.

[SwitchA] 

interface vlanif13

[SwitchA-Vlanif13] 

ip address 10.1.1.5 24

# Configure Switch B.

[SwitchB] 

interface vlanif13

[SwitchB-Vlanif13] 

ip address 10.1.1.6 24

[SwitchB-Vlanif13] 

quit

After the configuration, run the 

display interface vlanif

 command on Switch A or Switch B.

You can view that the status of VLANIF 13 is Up.

Step 3

Configure single-hop BFD on Switch A.

# Enable BFD on Switch A.

[SwitchA]

Step 4

Configure single-hop BFD on Switch B.

# Enable BFD on Switch B.

<Quidway>

 system-view

[Quidway]

 sysname SwitchB

Step 5

Verify the configuration.

After the configuration, run the 

display bfd session

 command on Switch A and Switch B. You

can view that the single-hop BFD session is set up and the status is Up.
