Abstract
A system and a method are disclosed for enabling interoperability between data plane learning endpoints and control plane learning endpoints in an overlay network environment. An exemplary method for managing network traffic in the overlay network environment includes receiving network packets in an overlay network from data plane learning endpoints and control plane learning endpoints, wherein the overlay network extends Layer 2 network traffic over a Layer 3 network; operating in a data plane learning mode when a network packet is received from a data plane learning endpoint; and operating in a control plane learning mode when the network packet is received from a control plane learning endpoint. Where the overlay network includes more than one overlay segment, the method further includes operating as an anchor node for routing inter-overlay segment traffic to and from hosts that operate behind the data plane learning endpoints.
