BGP Link-State Egress Peer Engineering
EPE or egress peer engineering will be configured mostly on the ASBRs where it labels the ASBR peer and the same information is shared with the controller using BGP LS. The controller should instruct PE to use a specific egress ASBR to reach a particular destination.The SR architecture defines three types of BGP Peering Segments that may be instantiated at a BGP node:
• Peer Node Segment (PeerNode SID) : instruction to steer to a specific peer node
• Peer Adjacency Segment (PeerAdj SID) : instruction to steer over a specific local interface towards a specific peer node
• Peer Set Segment (PeerSet SID) : instruction to load-balance to a set of specific peer nodes
