Configuring RSVP-TE Srefresh

Configuring RSVP-TE Srefresh

Enabling Summary Refresh (Srefresh) on interfaces connecting two RSVP neighboring nodes reduces the network cost and improves network performance. After Srefresh is enabled, retransmission of Srefresh messages will be automatically enabled on interfaces.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    mpls

    The MPLS view is displayed.

    Srefresh enabled in the MPLS view takes effect on an entire device.

  3. Run:

    mpls rsvp-te srefresh

    Srefresh is enabled.

  4. (Optional) Run:

    mpls rsvp-te timer retransmission { increment-value increment | retransmit-value interval } *

    The retransmission parameters are set.

  5. (Optional) Enable the summary refresh (Srefresh) forward compatibility.
    1. Run:

      quit

      The system view is displayed.

    2. Run:

      interface interface-type interface-number

      The view of the interface on which the MPLS TE tunnel is established is displayed.

    3. Run:

      mpls rsvp-te srefresh compatible

      The summary refresh (Srefresh) forward compatibility is enabled.

    When the primary and backup CR-LSPs share the same link, the node on both ends of the link may run different versions. If the upstream nodes run a version earlier than V8 and the downstream node runs V8, Srefresh incompatibility occurs. To address this problem, run the mpls rsvp-te srefresh compatible command on the interface that connects the downstream device to the upstream node to enable Srefresh compatibility.

    NOTE:

    This command can only be run on a downstream node running V8 when its upstream node runs a version earlier than V8, which ensures that Srefresh can be properly negotiated between the two nodes.

  6. Run:

    commit

    The configuration is committed.
