Configuring BFD Session Authentication Information

Configuring BFD Session Authentication Information

Context

NOTE:

This configuration applies only to multicast BFD session detection.

On a network demanding higher security, you can configure BFD session authentication information 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.

Procedure

  1. Run: system-view

    The system view is displayed.

  2. Run: bfd

    BFD is enabled globally.

  3. Run: quit

    The system view is displayed.

  4. Run: bfd bfd-name bind peer-ip default-ip interface interface-type interface-number [ source-ip source-ip ]

    A BFD session is created for detecting the physical link status.

  5. Run: authentication-mode met-sha1 key-id key-id-value cipher cipher-text nego-packet [ timeout-interval interval-value ]

    BFD session authentication information is configured.
