Egress Peer Engineering (EPE) is an application of Segment Routing
(SR) that solves the problem of egress peer selection. The SR-based
BGP-EPE solution allows a centralized controller, e.g., a
Software-Defined Network (SDN) controller, to program any egress
peer. The EPE solution requires the node or the SDN controller to
program 1) the PeerNode Segment Identifier (SID) describing a session
between two nodes, 2) the PeerAdj SID describing the link or links
that are used by the sessions between peer nodes, and 3) the PeerSet
SID describing any connected interface to any peer in the related
group. This document provides new sub-TLVs for EPE-SIDs that are used
in the Target FEC Stack TLV (Type 1) in MPLS Ping and Traceroute
procedures.
This document is a product of the Multiprotocol Label Switching Working Group
of the IETF.
This is now a Proposed Standard.
