SRv6 uSID Topology Discovery and Visualization by a PCE

The BGP-LS address family extensions allow the advertisement of SRv6 uSID topology information across all SRv6-capable nodes. In this test, we evaluated the PCE's capability to retrieve this SRv6 information, specifically the SRv6 uSID segments, SRv6 prefixes (locators), and the nodes and links attributes. The test setup consists of a PCE and PCC from different vendors, with an active BGP-LS session between them.
The test steps include:

• Establishing a BGP-LS session between the PCE and the PCC
• Retrieving topology data, including uSID topology
• Visualizing the SRv6 uSID topology on the PCE interface
