The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'SR-MPLS over IP' <draft-ietf-mpls-sr-over-ip-02.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2019-02-26. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract MPLS Segment Routing (SR-MPLS) is an MPLS data plane-based source routing paradigm in which the sender of a packet is allowed to partially or completely specify the route the packet takes through the network by imposing stacked MPLS labels on the packet. SR-MPLS could 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 preserving backward compatibility with SR-MPLS. This document describes how SR-MPLS capable routers and IP-only routers can seamlessly co-exist and interoperate through the use of SR-MPLS label stacks and IP encapsulation/tunneling such as MPLS-in- UDP as defined in RFC 7510.
