(Optional) Configuring PW APS

(Optional) Configuring PW APS

This section describes how to configure PW APS, so that a primary/secondary PW switchover can be performed if a PW fails.

Context

On a VPWS network where a PW protection group is configured, you can configure PW APS to ensure that if one PW in the protection group fails, the other PW takes over to forward traffic. To accelerate PW fault detection, configure MPLS OAM or MPLS-TP OAM.

Perform the following steps on the PEs at both ends of a PW:

Procedure

  1. Configure PW APS.
    1. Run system-view

      The system view is displayed.

    2. Run pw-aps aps-id

      A PW APS instance is created.

    3. (Optional) Run description

      A description is configured for the PW APS instance.

    4. Run quit

      Return to the system view.

    5. Run interface interface-type interface-number

      The AC interface view is displayed.

    6. Run mpls l2vpn pw-aps aps-id { admin | reference }

      The PW protection group is bound to the PW APS instance.

    7. Run quit

      Return to the system view.

    8. Run commit

      The configuration is committed.

  2. Configure OAM to detect PW faults.

    • Configure MPLS OAM to detect PW faults.
      1. Run system-view

        The system view is displayed.

      2. Run mpls

        The MPLS view is displayed.

      3. Run mpls oam

        MPLS OAM is enabled globally.

      4. Run quit

        Return to the system view.

      5. Run mpls-oam

        The MPLS OAM view is displayed.

      6. Run mpls oam l2vc peer-ip peer-ip vc-id vc-id vc-type vc-type [remote-peer-ip remote-peer-ip remote-vc-id remote-vc-id remote-vc-type remote-vc-type ] type { cv | ffd frequency ffd-fre } [ auto-protocol [ overtime overtime ] ]

        MPLS OAM parameters are configured.

      7. Run mpls oam l2vc enable { send | receive } { all | peer-ip peer-ip vc-id vc-id vc-type vc-type }

        MPLS OAM is enabled.

      8. Run quit

        Return to the system view.

      9. Run commit

        The configuration is committed.

    • Configure MPLS-TP OAM to detect PW faults.
      1. Run system-view

        The system view is displayed.

      2. Run mpls-tp meg meg-name

        A MEG is created, and the MEG view is displayed.

      3. Run me l2vc peer-ip peer-ip vc-id vc-id vc-type vc-type [ remote-peer-ip remote-peer-ip | ttl ttl-number ] mep-id mep-id remote-mep-id remote-mep-id

        An ME is created and bound to the PW.

      4. Run cc send enable

        CCM sending is enabled.

      5. Run cc receive enable

        CCM receiving is enabled.

      6. Run quit

        Return to the system view.

      7. Run commit

        The configuration is committed.
