This document defines a new SRv6 network function which can be used for SRv6 inter-layer network programming. It is a variant of the End.X function. Instead of pointing to an L3 adjacency, this function points to an underlay interface. Such a interface can stand for a underlay link or path/connection between two routers, which may be invisible in the L3 topology.
