(Optional) Binding OSPF IP FRR and BFD

(Optional) Binding OSPF IP FRR and BFD

Context

During the configuration of OSPF IP FRR, the lower layer needs to fast respond to the link change so that traffic can be rapidly switched to the backup link in the case of a link failure. Bind BFD to the link status so that link faults can be detected rapidly. This ensures that traffic is rapidly switched to the backup link in the case of link failures.

Binding OSPF IP FRR and BFD can be configured in a specified process or on a specified interface. The priority of BFD configured on an interface is higher than that of BFD configured in an OSPF process. If BFD is enabled on an interface, a BFD session is established according to the BFD parameters configured on the interface.

Procedure

  • Bind OSPF IP FRR and BFD in a specified process.
    1. Run system-view

      The system view is displayed.

    2. Run bfd

      BFD is globally configured.

    3. Run quit

      Return to the system view.

    4. Run ospf [ process-id | router-id router-id | vpn-instance vpn-instance-name ] *

      The OSPF process is enabled, and the OSPF view is displayed.

    5. Run bfd all-interfaces enable

      BFD is enabled in an OSPF process.

    6. Run bfd all-interfaces frr-binding

      IP FRR is bound to BFD in an OSPF process.

  • Bind OSPF IP FRR and BFD on a specified interface.
    1. Run system-view

      The system view is displayed.

    2. Run bfd

      BFD is globally configured.

    3. Run quit

      Return to the system view.

    4. Run interface interface-type interface-number

      The interface view is displayed.

    5. Run ospf bfd enable

      BFD on the specified interface is enabled with OSPF.

    6. Run ospf bfd frr-binding

      IP FRR is bound to BFD on the OSPF interface.
