EVPN Designs: EVPN IBGP over IPv4 EBGP
The article discusses a creative EVPN design using IBGP sessions over EBGP, highlighting the challenge of differing autonomous system assumptions and the solution of using BGP local AS functionality.
MAIN POINTS
- EVPN design involves running IBGP sessions over EBGP.
- IBGP assumes neighbors are in the same autonomous system.
- EBGP assumes neighbors are in different autonomous systems.
- BGP local AS functionality resolves the autonomous system mismatch.
TAKEAWAYS
- Creative EVPN designs can lead to complex configurations.
- Understanding BGP assumptions is crucial for network design.
- BGP local AS is a useful tool for resolving design issues.
- Networking vendors promote innovative yet challenging solutions.
