Procedure
Step 1 Assign IP addresses to the interfaces directly connecting Router A and Router B.
# Assign an IP address to the interface on Router A.
<HUAWEI> system-view
[HUAWEI] sysname RouterA
[RouterA] interface gigabitethernet
[RouterA-GigabitEthernet1/0/0] undo shutdown
[RouterA-GigabitEthernet1/0/0] ip address 10.1.1.1 24
[RouterA-GigabitEthernet1/0/0] quit
# Assign an IP address to the interface on Router B.
<HUAWEI> system-view
[HUAWEI] sysname RouterB
[RouterB] interface gigabitethernet 1/0/0
[RouterB-GigabitEthernet1/0/0] undo shutdown
[RouterB-GigabitEthernet1/0/0] ip address 10.1.1.2 24
[RouterB-GigabitEthernet1/0/0] quit
Step 2 Configure a BFD session with the one-arm Echo function.
# Configure Router A.
[RouterA] bfd
[RouterA-bfd] quit
[RouterA] bfd atob bind peer-ip 10.1.1.2 interface gigabitEthernet1/0/0 one-arm-
echo
[RouterA-bfd-session-atob] discriminator local 1
[RouterA-bfd-session-atob] min-echo-rx-interval 100
[RouterA-bfd-session-atob] commit
[RouterA-bfd-session-atob] quit
Step 3 Verify the configuration.
After the preceding configurations are complete, run the display bfd session all verbose
command on Router A. You can see that a single-hop BFD session has been created and its status
is Up.
<RouterA> display bfd session all verbose
