Abstract: Techniques for using policies in an overlay communication network are disclosed. These techniques include deriving a plurality of source tags for a flow relating to an overlay communication network, the plurality of source tags relating to one or more policies for the flow. The techniques further include deriving a tag pointer for the flow, the tag pointer corresponding to all of the plurality of source tags, encapsulating the tag pointer in the flow, and transmitting the flow over the overlay communication network, wherein the tag pointer is configured to be used to identify a plurality of policies for the flow on egress from the overlay communication network.
