A service provider offers video services on its DSL network. This service provider has multiple multicast-enabled edge routers that are connecting to its DSLAMs. Video is being delivered both as unicast and multicast. An operations engineer is faced with a troubleshooting scenario where the engineer wants to query a large number of edge routers to ensure that they have PIM neighbor relationship with upstream routers. The operations engineer also wants to check that one or more of the edge routers are IGMP queries on the interfaces that are connecting to DSLAMs. These tasks need to be accomplished without logging into each of the edge routers. Assume that the entire network is part of the same IGP and PIM topology. Which Cisco IOS show command or utility will achieve the needs of the operations engineer?
