Configuring BFD Session Authentication Information

This configuration applies only to multicast BFD session detection.

On a network demanding higher security, you can configure BFD session authentication information, including the authentication algorithm, authentication key, authentication key ID, and negotiation timeout interval, to improve network security. In a specific access scenario, for example, when a multicast BFD session is associated with the protocol status of an interface, you need to configure authentication information for the BFD session on the interface. BFD negotiation can succeed, the BFD-associated protocol status of the interface can be activated, and users can access the device through this interface only when the BFD session authentication information on both ends is consistent.
