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.
