Configuration Roadmap
The configuration roadmap is as follows:
Configure BFD sessions on RouterA and RouterB to detect faults on the link between RouterA
and RouterB.
Procedure
Step 1 Configure single-hop BFD on RouterA.
# Enable BFD on RouterA.
<Huawei> system-view
[Huawei] sysname RouterA
[RouterA] bfd
[RouterA-bfd] quit
# Create a BFD session on RouterA.
[RouterA] bfd atob bind peer-ip default-ip interface ethernet 2/0/0
[RouterA-bfd-session-atob] discriminator local 1
[RouterA-bfd-session-atob] discriminator remote 2
[RouterA-bfd-session-atob] commit
[RouterA-bfd-session-atob] quit
Step 2 Configure single-hop BFD on RouterB.
# Enable BFD on RouterB.
<Huawei> system-view
[Huawei] sysname RouterB
