Configuring Tunnel Reestablishment Parameters

Configuring Tunnel Reestablishment Parameters

Context

By configuring the tunnel reestablishment function, you can periodically recompute the route for a CR-LSP. If the route in recomputation is better than the route in use, a new CR-LSP is then established according to the recomputed route. In addition, services are switched to the new CR-LSP, and the previous CR-LSP is deleted.

Perform the following configurations on the ingress node of an MPLS TE tunnel.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface tunnel interface-number

    The tunnel interface view of the MPLS TE tunnel is displayed.

  3. Run mpls te timer retry interval

    The interval for re-establishing a tunnel is specified.

    By default, the interval for re-establishing a tunnel is 30 seconds.

  4. Run mpls te commit

    The current tunnel configuration is committed.

    If the establishment of a tunnel fails, the system attempts to reestablish the tunnel within the set interval and the maximum number of attempts is the set reestablishment times.
