1. A method comprising:
obtaining by an edge switch of an enterprise fabric a packet to be delivered to a client, wherein the packet includes a fabric tunnel encapsulation comprising a bearer indicator and a quality of service (QoS) indicator and is obtained via a fabric tunnel that is associated with a radio access bearer for the client;
removing the fabric tunnel encapsulation and providing an access tunnel encapsulation for the packet, wherein the bearer indicator and the QoS indicator are provided for the access tunnel encapsulation; and
forwarding the packet within the access tunnel encapsulation toward a cellular access point via an access tunnel, wherein the packet is to be transmitted to the client via the cellular access point.
