Dynamic Multipoint E-VPN. Using NHRP to build cross DC VxLAN Tunnels.
This work is based off opennhrp source code.
Like DMVPN which enables interconnection of layer-3 networks across
non-broadcast networks DMEVPN enables interconnecting layer-2 networks
across a non-broadcast networks (like Internet). Specifically, if you
have a requirement to extend Vxlan islands across a non-broadcast
network then you can use DMEVPN. DMEVPN can be an alternative to existing,
propiterary, offerings like EVPN.
