  1. Daniel Ginsburg Network Architect SR – Egress Peering Engineering

  2. Three components Distribution of External Topology and TE Information • Automated allocating of the related BGP Peering SID and FRR • Automated update of the peering characteristics: BW, Lat, SRLG… Centralized Decision Process • Collection of all paths from all peers, SLA information etc. • Decision for source nodes Programming TE policy • Implement the decision at the source nodes

  3. Problem:Need to make flexible exit-point selection decisions while separating decision policy and implementation mechanism

  4. BGP Peering SID PeerNode SID: local SID bound to an eBGP Peer • MPLS Dataplane: POP and forward on any interface to the peer PeerAdj SID: local SID bound to an external interface • MPLS Dataplane: POP and forward on the related interface PeerSet SID: local SID bound to a set of eBGP peers • MPLS Dataplane: POP and forward on any interface to the set of peers

  5. BGP Peering SID Upon the establishment of a peer, the related PeerNode SID is automatically allocated. If the peer is multi-hop, a PeerAdj SID is automatically allocated for any interface on the path to the peer A PeerSet must be defined by a policy provisioned by the operator. A PeerSet SID is allocated to any defined PeerSet
