(Optional) Configuring a Traffic Switching Policy for a Hot-Standby CR-LSP

This section describes how to configure a traffic switching policy for a hot-standby CR-LSP. The traffic switching policy determines whether to switch traffic back to the primary CR-LSP and sets a switchback delay.

Context

When a primary CR-LSP is Down, traffic switches to the hot-standby CR-LSP. When the primary CR-LSP is Up, traffic switches back by default. This configuration provides the flexibility to control the traffic switchover behavior.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface tunnel tunnel-number

    The view of the MPLS TE tunnel interface is displayed.

  3. Run:

    mpls te backup hot-standby mode { revertive [ wtr  interval ] | non-revertive }

    The traffic switching policy is configured for the hot-standby CR-LSP and the switchback delay is set.

  4. Run:

    commit

    The configurations are committed.
