Checking the Configurations
After configuring BFD to monitor an LDP LSP, you can view the configurations of the BFD session, such as the session type and status.
Procedure
- Run the display bfd session { all | static | dynamic | discriminator discr-value } [ verbose ] command to check information about BFD sessions.
- Run the display bfd statistics session { all | static | dynamic | discriminator discr-value | peer-ip peer-ip } command to check statistics about BFD sessions.
Example
Run the display bfd session all verbose command to view BFD session information.
