The IESG has received a request from the Inter-Domain Routing WG (idr) to consider the following document: - 'Advertising Segment Routing Policies in BGP' <draft-ietf-idr-sr-policy-safi-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 [email protected] mailing lists by 2024-11-11. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract A Segment Routing (SR) Policy is an ordered list of segments (i.e., instructions) that represent a source-routed policy. An SR Policy consists of one or more candidate paths, each consisting of one or more segment lists. A headend may be provisioned with candidate paths for an SR Policy via several different mechanisms, e.g., CLI, NETCONF, PCEP, or BGP. This document specifies how BGP may be used to distribute SR Policy candidate paths. It introduces a BGP SAFI to advertise a candidate path of a Segment Routing (SR) Policy and defines sub-TLVs for the Tunnel Encapsulation Attribute for signaling information about these candidate paths. This documents updates RFC9012 with extensions to the Color Extended Community to support additional steering modes over SR Policy.
