MPLS Segment Routing (SR-MPLS) is a method of source routing a packet
through an MPLS data plane by imposing a stack of MPLS labels on the
packet to specify the path together with any packet-specific
instructions to be executed on it.  SR-MPLS can be leveraged to
realize a source-routing mechanism across MPLS, IPv4, and IPv6 data
planes by using an MPLS label stack as a source-routing instruction
set while making no changes to SR-MPLS specifications and
interworking with SR-MPLS implementations.

This document describes how SR-MPLS-capable routers and IP-only
routers can seamlessly coexist and interoperate through the use of
SR-MPLS label stacks and IP encapsulation/tunneling such as
MPLS-over-UDP as defined in RFC 7510.

This document is a product of the Multiprotocol Label Switching Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
