Troubleshooting IGMP

No membership information on the receiver-side router
Symptom
When a host sends a report for joining the multicast group G, no membership information of the
multicast group G exists on the router closest to that host.
Solution
To resolve the problem:
Use the display igmp interface command to verify that the networking, interface connection,
1.
and IP address configuration are correct.
Use the display current-configuration command to verify that multicast routing is enabled. If
2.
it is not enabled, use the multicast routing command in system view to enable IP multicast
routing. In addition, verify that IGMP is enabled on the associated interfaces.
