Configuring PCEP on a PE Router

A Path Computation Client (PCC) supports the configurations related to the Path Computation Element (PCE) and communicates with Paragon Automation. However, you must configure PCEP on each PE router to configure the router as a PCC and establish a connection between the PCC and Paragon Automation. A PCC initiates path computation requests, which are then executed by Paragon Automation.

Configuring a PE Router as a PCC

To configure a PE router as a PCC:

  1. Enable external control of LSPs from the PCC router to Paragon Automation.

  2. Specify Paragon Automation (paragon) as the PCE that the PCC connects to, and specify the Paragon Automation host external IP address as the destination address.

    Note:

    The IP address that you specify here is the VIP address (pce-server-vip) that you have configured either during installation of the Paragon Automation cluster or post-installation of the cluster.

  3. Configure the destination port for the PCC router that connects to Paragon Automation (PCE server) using the TCP-based PCEP.

  4. Configure the PCE type.

  5. To verify that PCEP has been configured on the router, open a telnet session to access the router, and run the following commands:
