Abstract

   Egress Peer Engineering is an application of Segment Routing to solve
   the problem of egress peer selection.  The SR-based BGP-EPE solution
   allows a centralized (Software Defined Network, SDN)controller to
   program any egress peer.  The EPE solution requires a node to program
   PeerNodeSID, PeerAdjSID, PeerSetSID as described in
   [I-D.ietf-spring-segment-routing-central-epe].This document provides
   Target FEC stack TLV definitions as defined in [RFC8029] for the EPE
   SIDs.

1.  Introduction

   Egress Peer Engineering (EPE) as defined in
   [I-D.ietf-spring-segment-routing-central-epe] is an effective
   mechanism to select the egress peer link based on different criteria.
   The EPE SIDs provide means to represent egress peer links.  Many
   network deployments have built their networks consisting of multiple
   Autonomous Systems either for ease of operations or as a result of
   network mergers and acquisitons.  The egress links connecting the two
   Autonomous Systems could be managed using EPE-SIDs in this case as
   well.  It is important to be able to validate the control plane to
   forwarding plane synchronization for these SIDs so that any anomaly
   can be detected easily by the operator.

   This document provides Target FEC stack TLV definitions for EPE SIDs.
   Other procedures for mpls ping and traceroute as defined in [RFC8287]
   are applicable for EPE-SIDs as well.

2.  FEC Definitions

   As described in [RFC8287] sec 5, 3 new type of segment IDs are
   defined for the Target FEC stack TLV corresponding to each label in
   the label stack
