Abstract
An approach is provided for validating lower layer paths for higher layer networks. A request for path cost information is generated relating to a path traversing a first autonomous system and a second autonomous system, wherein each of the autonomous systems utilizes different cost metrics. The path cost information is received associated with reservation of capacity for the path. The path cost information is evaluated. The reservation is selectively accepted based on the evaluation.
