Abstract
Techniques are described for establishing a segment routed label switched path (LSP) regardless of whether a router along the shortest path is not enabled for segment routing. For example, a resource reservation LSP (e.g., a resource reservation protocol (RSVP) LSP) is established across the router that is not enabled for segment routing, such that the segment routed LSP may be established to tunnel through the resource reservation LSP. For example, when a centralized controller receives a request to establish a path using segment routing, one or more routers along the shortest path may not be enabled for segment routing. Instead of rejecting the request to establish the segment routed LSP in response to determining that one or more routers in a selected path are not enabled for segment routing, the controller may establish a resource reservation LSP to tunnel around the router that is not enabled for segment routing.
