Specifying a Candidate Server for a PCE Client

Specifying a Candidate Server for a PCE Client

Candidate servers can be specified for a PCE client to provide redundancy, which improves network reliability.

Usage Scenario

PCE+ devices are classified as servers and clients. A client sends a request to the server to calculate a path, and the server calculates a path. To specify a candidate PCE server for a PCE client, run the connect-server command.

Multiple candidate PCE servers can be specified for a PCE client.


  1. Run system-view

    The system view is displayed.

  2. Run pce-client

    The PCE client view.

  3. Run connect-server ip-address

    A candidate server is specified for the PCE client.

    The ip-address value is set to the source IP address of a PCE server. Repeat this step to specify multiple candidate servers to provide redundancy.

  4. (Optional) Run preference preference

    A preference value is assigned to a candidate PCE server.

    The preference value is an integer ranging from 0 to 7. The greater the value, the higher the preference.

    When multiple candidate servers are specified for a single client, they can be prioritized. A candidate server with the highest preference is selected to calculate paths.

    If no preference value is set, the default value 0 is used, indicating the lowest preference. If candidate servers have the same preference, the server with the smallest IP address is selected to calculate paths.

  5. Run commit

    The configuration is committed.
