A method is implemented by a network device functioning as an evolved universal terrestrial radio access network (E-UTRAN) node B (eNodeB) in a cellular communication network to support incremental deployment of identifier locator network protocol (ILNP) breakout in the cellular communication network. The method includes advertising a first access point name (APN) and a second APN to a user equipment (UE), where the first APN is associated with a user plane packet gateway (P-GWu) that is implemented at the source eNodeB, and where the second APN is associated with a packet gateway (P-GW) in a core of the cellular communication network.
