Use display igmp interface to view the IGMP configuration and operation information on an interface. For
example,
# Display the IGMP configuration and operation information on GigabitEthernet 1/0/1 of Router B.
[RouterB] display igmp interface GigabitEthernet 1/0/1 verbose
GigabitEthernet1/0/1(192.168.1.2):
IGMP proxy is enabled
Current IGMP version is 2
Multicast routing on this interface: enabled
Require-router-alert: disabled

Use display igmp group to view the IGMP group information. For example,
# Display the IGMP group information on Router A.
[RouterA] display igmp group
Total 1 IGMP Group(s).
Interface group report information of VPN-Instance: public net
GigabitEthernet1/0/1(192.168.1.1):
Total 1 IGMP Groups reported
Group Address
224.1.1.1
The output shows that IGMP reports from the hosts are forwarded to Router A through the proxy interface,
GigabitEthernet 1/0/1 of Router B.

Troubleshooting IGMP

No membership information on the receiver-side router

Symptom
When a host sends a report for joining multicast group G, no membership information of the multicast
group G exists on the router closest to that host.
