This document explains different tools and techniques for troubleshooting multicast networks. If you understand the various command line interface tools and the key information fields in their output, it helps you troubleshoot multicast networks. There are no specific requirements for this document.
This document is not restricted to specific software and hardware versions. The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command. Refer to for more information on document conventions. When you troubleshoot multicast networks, it is good to consider the signaling protocol used in the network and packet flow. The signaling protocol is used to setup and tear down the multicast sessions (such as PIM dense mode, PIM sparse mode, and DVMRP), and packet flow is the actual sending, replicating, and receiving of the multicast packets between the source and receiver, based on the forwarding table created by the signaling process.

This table helps verify each piece of troubleshooting information by checking that each section of the table is working correctly: Source Network Receivers Signaling NA Packet Flow The next subsections detail the troubleshooting tools you can use to check and fix common problems. Complete these steps to determine if the source is actually sourcing the packets and inserting the correct packet fields: • Check the interface counters on the host.
First, check the interface counters (if you are on a UNIX system, use the netstat command) on the source host to see if it is sending packets. If it is not, check for misconfiguration or bugs in the host stack and application. • Use the command to check the upstream router to see if it received a join membership report at the interface directly connected to source. • Check the TTL value in the application sourcing packets; it should be greater than 1. If the application sends packets with a TTL value less than 1, you should see the traffic dropped at the first upstream router. To verify, use the show ip traffic command and look for an increase in the value of the 'bad hop count' counter.
