Learn how to create explicit SR-MPLS policies using a fixed path consisting of a list of segment IDs (SIDs).

This task explains how to create SR-MPLS policies using an explicit (fixed) path. Each path consists of a list of prefix or adjacency Segment IDs (SID list), with each ID representing a node or link on the path.

Procedure

1.

Choose Services & Traffic Engineering > Traffic Engineering > SR-MPLS.

2.

Click Create > PCE Init.

Note

If you would like to provision a PCC initiated policy using Network Services Orchestrator (NSO) via the Crosswork Network Controller UI, see Create SR-TE policies (PCC-initiated).

3.

Under Policy details, enter or select the required SR-MPLS policy values. Hover over the Field Help icon icon to view a description of the field.

Tip

If you have set up device groups, you can select the device group from the Device groups drop-down list. Then navigate and zoom in on the topology map to click the device for headend or endpoint selection.

4.

Under Policy path, click Explicit path and enter a path name.

5.

Add segments to include in the SR-MPLS policy path.
6.

Click Preview and confirm that the policy you created matched your intent.

7.

To activate the policy on the network, click Provision.

8.

Validate the SR-MPLS policy creation:

  1. Confirm that the new SR-MPLS policy appears in the Traffic engineering table. Select the policy in the table to highlight it on the map.

    Note

    The newly provisioned SR-TE policy may take time to appear in the table, depending on network size and performance. The Traffic engineering table refreshes every 30 seconds.

  2. View and confirm the new SR-MPLS policy details. From the Traffic engineering table, click More icon and select View details.

Note

If the setup includes many nodes, policies, or interfaces, a timeout may occur during policy deployment. To configure timeout options, see Configure TE timeout settings.
