• A.Router 1 and Router 2 centrally learn the topology of the network to aid in SR-TE path selection for peers.
• B.Router 1 centrally learns the topology of the network to aid in SR-TE path selection, and Router 2 is a node that feeds Router 1 topology information.
• C.Router 2 is the head-end router in an SR-TE tunnel, and it is learning topology of the network from the PCE enabled on Router 1.
