Detailed Description

GENEVE.

GENEVE provides the features needed to allow L2 bridge domains (BDs) to span multiple servers. This is done by building an L2 overlay on top of an L3 network underlay using GENEVE tunnels.

This makes it possible for servers to be co-located in the same data center or be separated geographically as long as they are reachable through the underlay L3 network.
