A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Inter-Domain Routing Working Group of the IETF. Title : Segment Routing Egress Peer Engineering BGP-LS Extensions Authors : Stefano Previdi Clarence Filsfils Saikat Ray Keyur Patel Jie Dong Mach (Guoyi) Chen Filename : draft-ietf-idr-bgpls-segment-routing-epe-00.txt Pages : 18 Date : 2015-06-17 Abstract: Segment Routing (SR) leverages source routing. A node steers a packet through a controlled set of instructions, called segments, by prepending the packet with an SR header. A segment can represent any instruction, topological or service-based. SR allows to enforce a flow through any topological path and service chain while maintaining per-flow state only at the ingress node of the SR domain. The Segment Routing architecture can be directly applied to the MPLS dataplane with no change on the forwarding plane. It requires minor extension to the existing link-state routing protocols. This document outline a BGP-LS extension for exporting BGP egress point topology information (including its peers, interfaces and peering ASs) in a way that is exploitable in order to compute efficient Egress Point Engineering policies and strategies.
