HUAWEI NetEngine80E/40E Router
Configuration Guide - Reliability
The Eth-Trunk interfaces of Router A and Router B can ping each other.
[RouterA] ping -a 10.1.1.1 10.1.1.2
PING 10.1.1.2: 56
--- 10.1.1.2 ping statistics ---
Step 2 Configure single-hop BFD for a Layer 3 Eth-Trunk member link.
# Configure a BFD session on Router A and bind the member interface GE 1/0/0 to the BFD
session.
[RouterA] bfd
[RouterA-bfd] quit
[RouterA] bfd to_link1 bind peer-ip default-ip interface gigabitethernet 1/0/0
[RouterA-bfd-session-to_link1] discriminator local 10
[RouterA-bfd-session-to_link1] discriminator remote 11
[RouterA-bfd-session-to_link1] wtr 5
[RouterA-bfd-session-to_link1] commit
[RouterA-bfd-session-to_link1] quit
# Configure the BFD session on Router B and bind the member link interface GE 1/0/0.
[RouterB] bfd
[RouterB-bfd] quit
[RouterB] bfd to_link1 bind peer-ip default-ip interface gigabitethernet 1/0/0
[RouterB-bfd-session-to_link1] discriminator local 11
[RouterB-bfd-session-to_link1] discriminator remote 10
[RouterB-bfd-session-to_link1] wtr 5
[RouterB-bfd-session-to_link1] commit
[RouterB-bfd-session-to_link1] quit
Step 3 Verify the configuration.
After the configurations, run the display bfd session all verbose command on Router A and
Router B. You can view that the 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
