EVPN in Campus Networks

Time 12/10/19 02:40PM-03:10PM

Session Abstract


The University of Minnesota recently deployed a next-generation multi-campus statewide network using Ethernet VPN (EVPN) as a foundational technology. EVPN with BGP as the control plane has been deployed in the general campus networks, the data center networks, and in the network-services networks. While BGP and EVPN are the control plane, various data plane encapsulation types are in use, depending on the needs: MPLS, VXLAN, and GRE.

Some benefits are no more pseudowires or VPLS, new redundancy options for the access-layer such as Anycast Gateway and Multi-Chassis LAG, BGP as a common control plane, MAC address and MAC/IP binding visibility in BGP.

This session will cover some of the architectural decisions made by Minnesota as well as some of the lessons learned during testing and deployment (e.g. scaling considerations, new loop-prevention needs, and more).

Also, the Cisco Campus Fabric architecture will be covered and how it could be used to deploy traditional and new Carrier Ethernet services using BGP-based control plane and EVPN technologies. Covering typical use cases, implementation details, platform considerations such as scalability, IOS XR configurations and verification commands for point-to-point and point to multipoint services in an end to end architecture.
