16.6.5 IGMP Troubleshooting
In configuring and using IGMP Protocol, IGMP Protocol might not operate normally
caused by physical connection or incorrect configuration. Therefore, user should pay
attention to the following issues:
z Firstly to assure that physical connection is correct.
z Next, to assure the Protocol of Interface and Link protocol is UP (use show interface
command);
z Afterwards, to assure to start a kind of multicast protocol on the interface;
z Multicast Protocol requires RPF Check using unicast routing; therefore the
correctness of unicast routing must be assured beforehand.
If all attempts including Check are made but the problems on IGMP can’t be solved
yet, then use debug commands such debug ipv6 mld event/packet please, and then copy
DEBUG information in 3 minutes and send to Technology Service Center.
