Local area network architecture for supporting multiple IP services

A network device receives an indication to establish a session for an internet protocol (IP) service between a first device and a second device, wherein the network device is part of a local network with the first device and another network device. The network device identifies a service tag to include in a service tag field of a session request. The other network device causes the session request that includes an updated service tag to be provided to the second device. The second device provides a session response with the service tag to the other network device, the other network device updates the session response to include the original service tag and provides an updated session response to the network device. The network device causes the session to be established.
