BFD Configuration

The following sections provide conceptual information about BFD configuration. For detailed procedural information about BFD configuration, see BFD Configuration using CLI and BFD Configuration using EDM.

Enable BFD

To enable Bidirectional Forwarding Detection (BFD) between 2 peers:

  1. Configure BFD globally.
  2. Configure BFD on the required interfaces of both peer systems.
  3. Enable BFD on the required routing protocols.
  4. Specify the next-hop device with which the switch initiates the BFD session.

Delete a BFD Session

To delete a BFD session, disassociate all applications with the BFD session, then administratively bring down the BFD session.

Note

Note

To successfully delete a BFD session, you must run the commands in the following order:

  1. Disassociate all applications from the BFD session.
  2. Disable BFD at the global level or interface level, which transitions the BFD session to the AdminDown state.

If you change the order of operations, the BFD session is not deleted.
