On today’s Priority Queue, we explore DMEVPN, a open-source, proof of concept technology using a DMVPN-like construct for multipoint EVPN tunnels. By using DMEVPN, network engineers can extend layer-2 tunnels across an external IP network.
Joining us today is Saurabh Mohan, a software engineer who’s been building software products for the networking space for over 15 years now. Saurabh wrote up a detailed post on the DMEVPN code he’s created that actually works and is available on GitHub.
We get details from Saurabh on DMEVPN, how it differs from DMVPN, the use cases for DMEVPN implementations, and even a packet walk to to illustrate how it works. We also dive into VXLAN, NHRP, and IPSec. Strap in because this one gets nerdy.
