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.
