Fully Meshed Network
In a fully meshed VXLAN network, every VTEP is configured with a tunnel to every other VTEP running the same VNI. A fully meshed VXLAN network allows for any overlay network to reach any other part of the network for local L2 to L2 traffic. This is necessary when client to client traffic is needed among roaming clients with the same subnet.

Every VTEP needs 6 Tunnel connections to reach every other VTEP in the mesh network.
