Enabling Reservation Confirmation Mechanism

Enabling Reservation Confirmation Mechanism

Context

Receiving an ResvConf message does not mean that the resource reservation succeeds. It means that resources are reserved successfully only on the farthest upstream node where this Resv message arrives. These resources, however, may be preempted by other applications later. You can enable reservation confirmation mechanism to prevent this problem.

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

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run mpls

    The MPLS view is displayed.

  3. Run mpls rsvp-te resvconfirm

    The reservation confirmation mechanism is enabled.

    The reservation confirmation is initiated by the receiver of Path message. An object that requires confirming the reservation is carried along the Resv message sent by the receiver.
