1. A first network device, comprising:
one or more processors configured to:
identify a first interface between the first network device and a second network device, which is associated with a session management function and a packet data gateway control plane function of a core network;
send an association message to the second network device via the first interface;
receive, from the second network device via the first interface, selection information;
send, via a second interface between the first network device and the second network device, a request related to creation of a packet data network (PDN) session for a user device to the second network device;
receive, from the second network device via the second interface, a response related to the creation of the PDN session;
select, based on the response and the selection information, a third network device associated with a serving gateway user plane function of the core network; and
send an additional association message to the third network device via a third interface between the first network device and the third network device to cause:
the third network device to be associated with a data network; and
the third network device to route traffic for the PDN session between the user device and the data network.
