Solution Development Ideally any potential solutions should look to reuse existing techniques. Obvious candidate is LSP Ping P2P LSP Ping Ping to verify the LSP connectivity. Traceroute to identify LSP paths as well as fault isolation. Return codes to indicate possible errors. Adapting P2P LSP Ping for P2MP networks Scaling ping Handling multiple recipient echo replies. Ability to target specific recipients. Scaling trace Tracing across point-to-multipoint tree topologies. Displaying transit and branching routers. Security & bandwidth handling DOS attacks.
