TX : 10
RX : 10
Multiplier : 3
Diag : No diagnostic information
Total BFD session(s): 2
From the preceding display, you can view that the status of the BFD session between Router A
and Router B and that between Router A and Router C are Up.
Step 5 Configure BFD of the interfaces.
# Configure BFD on GE 2/0/0 of Router 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.
[RouterA] interface gigabitethernet 2/0/0
[RouterA-GigabitEthernet2/0/0] isis bfd enable
[RouterA-GigabitEthernet2/0/0] isis bfd min-tx-interval 100 min-rx-interval 100
detect-multiplier 4
[RouterA-GigabitEthernet2/0/0] quit
# Configure BFD on GE 2/0/0 of Router 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.
[RouterB] bfd
[RouterB-bfd] quit
[RouterB] interface gigabitethernet 2/0/0
[RouterB-GigabitEthernet2/0/0] isis bfd enable
[RouterB-GigabitEthernet2/0/0] isis bfd min-tx-interval 100 min-rx-interval 100
detect-multiplier 4
[RouterB-GigabitEthernet2/0/0] quit
# After the preceding configurations are complete, run the display isis bfd session all command
on Router A or Router B. You can view that the parameters of the BFD have taken effect. Take
the display of Router B as an example:
[RouterB] 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
Total BFD session(s): 2
Step 6 Verify the configuration.
# Run the shutdown command on GE 2/0/0 of Router B to simulate the active link failure.
[RouterB] interface gigabitethernet 2/0/0
[RouterB-GigabitEthernet2/0/0] shutdown
Step 7 # Display the routing table on Router A.
[RouterA] display ip routing-table
