7 Verifying L3VPN interoperability in certain cases is a significant first step intended to prove that our test bed allows complete functionality and validation of making any sophisticated evaluations. As in the past, the process started with verifying the functionality of the control‐plane BGP and the corresponding IGP against the correct Segment Routing (SR) MPLS label configuration. Since all the above elements were tested and found to be functional, L3VPN services were activated, and the IPv4 and IPv6 traffic was sent into the network to check the end‐to‐end connectivity.

13 Two topologies were used in testing this year’s systems: an IS‐IS‐based network design consisting of two spine nodes and an OSPF‐based network design comprising one spine node. In both versions, the router forwarding tables needed to be analyzed to determine whether the route was inserted correctly. Ultimately, we established the traffic flows on every available link, resulting in no packet loss in any streams. The results confirm that the infrastructure for SR‐MPLS–based L3VPN is reliable, allowing more service validation in the next phase of tests.
