Abstract

Techniques are described for dynamically computing a segment routing policy for a segment routing for traffic engineering (SR-TE) path. For example, in a discontinuous SR network in which SR islands (e.g., groups of neighboring routers that are enabled for segment routing) are separated by one or more routers not enabled for segment routing, instead of returning a failure because one or more routers along a path are not enabled for SR, an ingress router may generate an SR-TE operations, administrations, and management (OAM) Multi-Protocol Label Switching (MPLS) traceroute packet send the packet to a first border router of the RSVP-enabled devices along a computed path to trigger the creation of a resource reservation Label Switched Path (LSP) through the RSVP-enabled devices. In this way, segment routed LSP may be established to tunnel through the resource reservation LSP for a SR-TE path used in an SR-TE policy.
