The IP-Trunk interface of Router A and the IP-Trunk interface of Router B can ping each other.
Use the display on Router A as an example.
[RouterA] ping 100.1.1.2
PING 100.1.1.2: 56
--- 100.1.1.2 ping statistics ---
Step 2 Configure the one-hop BFD for the IP-Trunk.
# Enable BFD on Router A, configure a BFD session between Router A and Router B, and bind
Router A's IP-Trunk interface to the BFD session.
[RouterA] bfd
[RouterA-bfd] quit
[RouterA] bfd atob bind peer-ip 100.1.1.2 interface ip-trunk 1
[RouterA-bfd-session-atob] discriminator local 10
[RouterA-bfd-session-atob] discriminator remote 20
[RouterA-bfd-session-atob] wtr 5
[RouterA-bfd-session-atob] commit
[RouterA-bfd-session-atob] quit
# Enable BFD on Router B, configure the BFD session between Router B and Router A, and
bind Router B's IP-Trunk interface to the BFD session.
[RouterB] bfd
[RouterB-bfd] quit
[RouterB] bfd btoa bind peer-ip 100.1.1.1 interface ip-trunk 1
[RouterB-bfd-session-btoa] discriminator local 20
[RouterB-bfd-session-btoa] discriminator remote 10
[RouterB-bfd-session-btoa] wtr 5
[RouterB-bfd-session-btoa] commit
[RouterB-bfd-session-btoa] quit
Step 3 Verify the configuration.
After the configurations, run the display bfd session all verbose command on Router A or
Router B. You can view that a single-hop BFD session has been set up and its status is Up.
Use the display on Router A as an example.
[RouterA] display bfd session all verbose
