From the preceding display, you can view that the status of the BFD session between Switch A
and Switch B and that between Switch A and Switch C are Up.
Step 6 Configure BFD of the interfaces.
# Configure BFD on Vlanif20 of Switch A, set the minimum interval for sending the packets
and the minimum interval for receiving the packets to 100 ms, and set the local detection time
multiple to 4.
[SwitchA] interface vlanif 20
[SwitchA-Vlanif20] isis bfd enable
[SwitchA-Vlanif20] isis bfd min-tx-interval 100 min-rx-interval 100 detect-
multiplier 4
[SwitchA-Vlanif20] quit
# Configure BFD on Vlanif20 of Switch B, set the minimum interval for sending the packets
and the minimum interval for receiving the packets to 100 ms, and set the local detection time
multiple to 4.
[SwitchB] bfd
[SwitchB-bfd] quit
[SwitchB] interface vlanif 20
[SwitchB-Vlanif20] isis bfd enable
[SwitchB-Vlanif20] isis bfd min-tx-interval 100 min-rx-interval 100 detect-
multiplier 4
[SwitchB-Vlanif20] quit
# After the preceding configurations are complete, run the display isis bfd session all command
on Switch A or Switch B. You can view that the parameters of the BFD have taken effect. Take
the display of Switch B as an example:
[SwitchB] display isis bfd session all
Peer System ID : 0000.0000.0001
TX : 100
RX : 100
Multiplier : 4
Diag : No diagnostic information
Peer System ID : 0000.0000.0003
TX : 100
RX : 100
Multiplier : 3
Diag : No diagnostic information
Step 7 Verify the configuration.
# Run the shutdown command on Vlanif20 of Switch B to simulate the active link failure.
[SwitchB] interface vlanif 20
[SwitchB-Vlanif20] shutdown
Step 8 # Display the routing table on Switch A.
[SwitchA] display ip routing-table
