Claim:
1. A method comprising: obtaining a router list of edge routers in a multicast network; receiving a stream list of multicast streams flowing through the edge routers; in response to determining that a rendezvous point associated with a particular stream is valid, determining, based on a first query response that corresponds to the particular stream, whether a prune flag is set for the particular stream; in response to determining that the prune flag is not set, determining, based on a second query response that corresponds to the particular stream, whether a shortest path tree flag is set for the particular stream, wherein the second query response corresponds to a second query of a management information base (MIB) database, and wherein the shortest path tree flag being set indicates that the particular stream is valid; and in response to determining that the shortest path tree flag is set, generating an output indicating that the particular stream is valid.
