Configuring Static BFD for TE with Automatically Negotiated Discriminators
This section describes how to configure a static BFD session with automatically negotiated discriminators to detect TE tunnel faults.
Applicable Environment
When configuring a static BFD session with automatically negotiated discriminators to detect TE tunnel faults, you can specify a reverse tunnel. In this way, you do not need to manually plan or configure BFD session discriminators, simplifying the configuration.
Pre-configuration Tasks
Before configuring static BFD for TE with automatically negotiated discriminators, configure MPLS TE tunnels.
Context
Procedure
- Run system-view
The system view is displayed.
- Run bfd
BFD is enabled globally on the local node, and the BFD view is displayed.
Configurations relevant to BFD can be performed only after the bfd command is run globally.
- Run quit
The system view is displayed.
- Run bfd sessname-value bind mpls-te interface { tunnel-type tunnel-num } [ te-lsp [ backup ] ] [ reverse-te lsr-id lsr-id tunnel-id tunnel-id auto ]
BFD with automatically negotiated discriminators is configured to detect TE tunnel faults.
In the command, reverse-te lsr-id lsr-id tunnel-id tunnel-id parameters specify reverse TE tunnel information.
- Run quit
The system view is displayed.
- Run commit
The configurations are committed.
Verifying the Configuration
After completing the preceding configuration, run the display bfd session command. The command output shows that the BFD session status is UP.
