Abstract:
1. A method for verifying a path, comprising: generating a request for information associated with a service-based distribution path comprising a service distribution point and one or more transport tunnels associated with the service distribution point; sending the request to a far-end destination associated with the service distribution point; and receiving a reply to the request, wherein the service distribution point is configured to have one or more services associated with it and to use the one or more transport tunnels to transport to a provider edge device on a far end of a provider network data associated with the one or more services; and wherein the request is sent by or on behalf of a near-end node associated with the service distribution point; said information associated with a service-based distribution path comprises information that indicates how a service associated with the service distribution path is configured at said far end destination; and said information associated with the path is processed to determine whether the information included in the reply is consistent with how the service is configured at the near-end node.
