The IESG has received a request from the Inter-Domain Routing WG (idr) to consider the following document: - 'BGP Classful Transport Planes' <draft-ietf-idr-bgp-ct-34.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 2025-02-07. 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 specifies a mechanism referred to as "Intent Driven Service Mapping". The mechanism uses BGP to express intent based association of overlay routes with underlay routes having specific Traffic Engineering (TE) characteristics satisfying a certain Service Level Agreement (SLA). This is achieved by defining new constructs to group underlay routes with sufficiently similar TE characteristics into identifiable classes (called "Transport Classes"), that overlay routes use as an ordered set to resolve reachability (Resolution Schemes) towards service endpoints. These constructs can be used, for example, to realize the "IETF Network Slice" defined in TEAS Network Slices framework. Additionally, this document specifies protocol procedures for BGP that enable dissemination of service mapping information in a network that may span multiple cooperating administrative domains. These domains may be administered either by the same provider or by closely coordinating providers. A new BGP address family that leverages RFC 4364 ("BGP/MPLS IP Virtual Private Networks (VPNs)" procedures and follows RFC 8277 ("Using BGP to Bind MPLS Labels to Address Prefixes") NLRI encoding is defined to enable each advertised underlay route to be identified by its class. This new address family is called "BGP Classful Transport", a.k.a., BGP CT.
