Use this procedure to view and analyze point-to-multipoint multicast trees in the topology map using Crosswork Network Controller.

Before you begin

To visualize multicast trees in the topology map, Tree-SID policies must be configured in your network. For more information, see the SR Tree-SID configuration documentation for your specific device (for example, Segment Routing Configuration Guide for Cisco NCS 540 Series Routers).

Crosswork Network Controller allows you to visualize Tree-SID policies configured in your network.

The example shows a representation of a Tree-SID policy in the topology map. The root node (R) and leaf nodes (L) are marked, and the arrows indicate the path through the transit nodes from the root to the leaf nodes.

Procedure

1.

From the main menu, select Services & Traffic Engineering > Traffic Engineering > Tree-SID.

2.

Select the Tree-SID policies you want to view on the topology map. Only two policies can be displayed on the topology map at a time.

Note

Any change in end-points is recorded as an event in the historical data tab. For information about Tree-SID historical data, see View TE event and utilization history.

3.

To view Tree-SID details, from the Actions column, click More icon > View details for one of the Tree-SID policies. You will see a summary and Tree-SID path information.

Example:

Note

  • A (Compute) label, next to the SR-PCE field identifies the SR-PCE used to create the policies.

  • If a source node is unavailable, a warning icon and message appear next to the Oper Status field. Hover the mouse over the warning icon to see where the connection issue is located.
