MPLS/VPN with SR-MPLS Core
SR-MPLS can replace the traditional MPLS control plane in a BGP-free core and still support MPLS/VPN services effectively, as shown in the second “fun” scenario of an ITNOG10 Segment Routing workshop using the same topology as the earlier BGP-free core example.
MAIN POINTS
- SR-MPLS serves as a drop-in replacement for the traditional MPLS control plane.
- Properly implemented SR-MPLS works well with MPLS/VPN services.
- The workshop’s second “fun” scenario demonstrates this behavior.
- The scenario uses the same topology as the BGP-free core example.
TAKEAWAYS
- SR-MPLS can simplify core design without changing the overall service model.
- MPLS/VPN remains compatible with segment routing in a BGP-free environment.
- Reusing the same topology helps compare traditional MPLS and SR-MPLS approaches.
- The example reinforces SR-MPLS as a practical alternative for core transport.
