The IESG has received a request from the Inter-Domain Routing WG (idr) to consider the following document: - 'BGP Color-Aware Routing (CAR)' <draft-ietf-idr-bgp-car-11.txt> as Experimental RFC
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 2025-02-13. 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 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.
