7 SRv6 µSIDs enable compact, scalable service programming, but their correct use in a controller-based environment depends on accurate topology information. For reliable end-to-end path validation, the controller must correctly learn and interpret SRv6-specific attributes such as adjacency SIDs, endpoint behaviors, and C-SID structure parameters.
8 In this test, we verified SRv6 µSID discovery using BGP-LS in a multi-vendor environment. We validated that IS-IS SR extensions for SRv6 were correctly exported by routers and parsed and applied by the centralized controller.
9 BGP-LS sessions between the controller and network nodes were successfully established. The controller received SRv6 capability information, including End.X adjacency SIDs with their SID values and endpoint behaviors.
10 Compressed SID (C-SID) structure parameters were correctly advertised and received. SRv6 adjacency SIDs were correctly associated with their respective links in the topology database.
