Enabling non-flexible-algorithm routers to participate in flexible-algorithm routing protocols

Abstract:

Techniques are described for facilitating the inclusion of a non-flexible-algorithm router to be included in flexible-algorithm path computations. For example, a flexible-algorithm router advertises information associated with a non-flexible-algorithm router to other flexible-algorithm routers in the network such that the flexible-algorithm routers may include the non-flexible-algorithm router when computing a path based on flexible-algorithm. During path computation, if the router determines that its next-hop router is the non-flexible-algorithm router, the router may configure additional forwarding information to cause the router to steer traffic to the non-flexible-algorithm router.
