Abstract
Systems, methods, and computer-readable media are provided for enforcing policy for upstream (e.g., traffic from an endpoint to the physical network layer or hardware fabric of a data center) flood traffic (e.g., broadcast, unknown unicast, or multicast traffic) originating from a virtual endpoint via a network fabric. In one embodiment, upstream flood traffic can be transmitted using a special multicast group to which only elements of the data center fabric (e.g., physical switches, routers) are subscribed. That is, upstream flood traffic is assigned to the special multicast group, resulting in unintended endpoints not receiving the flood traffic. However, the hardware fabric receives the flood traffic and will then enforce applicable policies to route the packets to intended endpoints.
