Lukas Krattiger (@CCIE21921), Technical Marketing Engineer and Samir Thoria, Principal Engineer at Cisco join Ethan Banks and Greg Ferro for a discussion of how the Cisco Nexus 9K switching platform can use BGP as a control plane for VXLAN. If that sentence made your head hurt, let’s condense this discussion down to the following points.
- VXLAN needs a control plane. IETF does not specify one.
- The EVPN folks are using BGP for their control plane.
- Cisco has adapted BGP for EVPN as BGP for VXLAN.
- Voila! BGP as a VXLAN control plane. Supported today on NX9K kit. Tomorrow on more Cisco kit.
- Cisco is working with the IETF to extend the EVPN/BGP control plane to accommodate their work with VXLAN/BGP.
Got it? Not yet? Perfect. Then you’ll have to listen to the show and follow up with some reading & further listening. You know, like in the links below.
