The MPLS source routing mechanism can be leveraged to realize a unified source routing instruction which works across both IPv4 and IPv6 underlays in addition to the MPLS underlay. This document describes how to leverage the unified source routing instruction to realize a transport-independent service function chaining by encoding the service function path information or service function chain information as an MPLS label stack.}, }
