Administrator Guide

The mtrace command traverses the path of the response data block in the reverse direction of the multicast data
traffic. The mtrace command traverses the reverse path to the source from the destination. As a result, the
tabular output of the mtrace command displays the destination details in the first row, followed by the RPF router
details along the path in the consequent rows, and finally the source details in the last row. The tabular output
contains the following columns:
• Hop — a hop number(counted negatively to indicate reverse-path)
• OIF IP — outgoing interface address
• Proto — multicast routing protocol
• Forwarding code — error code as present in the response blocks
• Source Network/Mask — source mask
show ip multicast-cam
