The IESG has received a request from the Inter-Domain Routing WG (idr) to consider the following document: - 'Segment Routing Prefix SID extensions for BGP' <draft-ietf-idr-bgp-prefix-sid-09.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 2018-01-26. 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 Segment Routing (SR) architecture allows a node to steer a packet flow through any topological path and service chain by leveraging source routing. The ingress node prepends an SR header to a packet containing a set of segment identifiers (SID). Each SID represents a topological or a service-based instruction. Per-flow state is maintained only on the ingress node of the SR domain. This document defines an optional, transitive BGP attribute for announcing BGP Prefix Segment Identifiers (BGP Prefix-SID) information. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-idr-bgp-prefix-sid/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-idr-bgp-prefix-sid/ballot/ No IPR declarations have been submitted directly on this I-D.
