Abstract: Disclosed herein are systems, methods, and computer-readable media for managing Layer 2 (L2) and Layer 3 (L3) policies. Traffic is routed from a first VM to a first CGW within a Service Node, where the Service Node can include a centralized policy for both L2 functions and L3 functions, and the first CGW can integrate both L2 gateways and L3 gateways. Based on a floating IP address of the packet, the traffic is routed within the Service Node, the traffic being routed by an access BD from an ingress BD-VIF to an egress BD-VIF. The traffic is then routed from a second CGW that integrates both L2 gateways and L3 gateways to the destination VM.

Abstract: In one embodiment, a method includes identifying at a first edge device, a failure at a second edge device, the first and second edge devices located in a local network site in communication with remote network sites in an overlay network, changing a state of a routing locator address at the first edge device from down to up in response to the failure at the second edge device, the routing locator address initially associated with the second edge device, and advertising the routing locator address at the first edge device in an underlay network so that packets from the remote network sites are forwarded to the first edge device upon convergence in the underlay network. An apparatus and logic are also disclosed herein.
