(Optional) Configuring PCE to Calculate a Path Crossing Both the IP and Optical Layers

A specific path calculation mode must be planned for a GMPLS UNI tunnel.

Context

The NetEngine 8000 F calculates a path for a GMPLS UNI tunnel in either of the following modes:

Independent path calculation at IP and optical layers
PCE path calculation for a path crossing the IP and optical layers

The independent path calculation mode is enabled by default. PCE path calculation can be configured to calculate a path crossing both the IP and optical layers.

Procedure

Configure the ingress EN to send a request to a PCE server to calculate a path crossing both the IP and optical layers.
1. Run system-view
  The system view is displayed.
2. Run mpls
  The MPLS view is displayed.
3. Run mpls te pce inter-layer delegate
  The ingress EN is configured to send a request to a PCE server to calculate a path crossing both the IP and optical layers.
4. Run commit
  The configuration is committed.
Specify a candidate server for a PCE client.
(Optional) Configure PCEP session authentication.
(Optional) Configure timers for a PCE client.
