摘要
Techniques are described for providing end-to-end segment routing paths across metropolitan area networks. For example, a method comprises receiving, by an area border router (ABR) connected to one or more metropolitan area networks and a core network, a packet including a segment routing label stack including at least a label of the ABR, a context label associated with a routing instance of the ABR, and a subsequent label identifying a device in the segment routing path, determining, from a lookup of the context label in the metro routing table, a table next hop to the core routing table (or metro routing table); in response to determining the table next hop, determining, from a lookup of the subsequent label in the core routing table (or metro routing table), a next hop in the segment routing path; and sending, by the ABR, the packet toward the device in the segment routing path.
