A method implemented by a user equipment (UE) in a cellular communication network to support incremental deployment of identifier locator network protocol (ILNP) breakout. The method includes receiving an advertisement for a first access point name (APN) and a second APN from a source eNodeB, 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, establishing a first PDN session associated with the first APN, establishing a second PDN session associated with the second APN, sending traffic destined for a first Correspondent Node (CN) that is determined to be ILNP capable via the first PDN session, and sending traffic destined for a second CN that is determined not to be ILNP capable via the second PDN session.
