Configuring Association Between a BFD Session and an Interface to Trigger the Associated Interface in Down State

Configuring Association Between a BFD Session and an Interface to Trigger the Associated Interface in Down State

Pre-configuration Tasks

Before configuring association between a BFD session and an interface, create a BFD session.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run oam-mgr

    The OAM management view is displayed.

  3. Run the following commands as required.

    • Run oam-bind ingress bfd-session bfd-session-id trigger if-down egress interface interface-type interface-number

      A BFD session is configured to report faults to an interface.

      By default, a BFD session is not enabled to report faults to an interface.

      When a BFD session detects a fault, the physical status of the interface bound to the BFD session becomes Down.

    • Run oam-bind ingress interface interface-type interface-number egress bfd-session bfd-session-id trigger if-down

      An interface is configured to report faults to a BFD session.

      By default, an interface is not enabled to report faults to a BFD session.

      When an interface becomes Down, the OAM management module sends a fault notification message to the BFD session bound to the interface. Then the fault notification message is sent to the remote device through the BFD session.

    • Run oam-bind bfd-session bfd-session-id trigger if-down interface interface-type interface-number

      The BFD session and the interface are configured to report faults to each other.

      By default, a BFD session and an interface are not enabled to report faults to each other.

      NOTE:

      If the oam-bind bfd-session bfd-session-id trigger if-down interface interface-type interface-number command is run, the oam-bind ingress bfd-session bfd-session-id trigger if-down egress interface interface-type interface-number and oam-bind ingress interface interface-type interface-number egress bfd-session bfd-session-id trigger if-down commands will be displayed in the configuration file.

      The physical interface associated with BFD cannot be the interface of the BFD link. Otherwise, a link deadlock occurs.
