The IESG has approved the following document: - 'BGP Color-Aware Routing (CAR)' (draft-ietf-idr-bgp-car-16.txt) as Experimental RFC
This document is the product of the Inter-Domain Routing Working Group. The IESG contact persons are Gunter Van de Velde, Jim Guichard and John Scudder. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-idr-bgp-car/ Technical Summary This document describes a BGP based routing solution to establish end-to-end intent-aware paths across a multi-domain transport network. The transport network can span multiple service provider and customer network domains. The BGP intent-aware paths can be used to steer traffic flows for service routes that need a specific intent. This solution is called BGP Color-Aware Routing (BGP CAR). This document describes the routing framework and BGP extensions to enable intent-aware routing using the BGP CAR solution. The solution defines two new BGP SAFIs (BGP CAR SAFI and BGP VPN CAR SAFI) for IPv4 and IPv6. It also defines an extensible NLRI model for both SAFIs that allow multiple NLRI types to be defined for different use cases. Each type of NLRI contains key and TLV based non-key fields for efficient encoding of different per-prefix information. This specification defines two NLRI types, Color-Aware Route NLRI and IP Prefix NLRI. It defines non-key TLV types for MPLS label stack, Label Index and SRv6 SIDs. This solution also defines a new Local Color Mapping (LCM) Extended Community. Working Group Summary The shepherd writeup provides a detailed timeline and explanation of the WG process. The eventual consensus to publish as experimental reflects engagement from the WG, the various draft proponents, the chairs, and the past and present ADs. Document Quality There are three implementations reported; see the shepherd writeup for details. Personnel The Document Shepherd for this document is Susan Hares. The Responsible Area Director is John Scudder. _______________________________________________ IETF-Announce mailing list -- [email protected] To unsubscribe send an email to [email protected]
