(Optional) Binding OSPF IP FRR and BFD

(Optional) Binding OSPF IP FRR and BFD

This section describes how to bind OSPF IP FRR and BFD 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.

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 configure 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 set on the interface.

Procedure

  • Binding 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.

  • Binding 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

      The 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.
