11.5.1.4 MLD Troubleshooting Help

When configuring and using MLD protocol, MLD protocol may fail to work normally

due to physical connections, incorrect configuration and so on. So, users shall note the

following points:

 Assure the physical connection is correct.

 Assure the protocol of interface and link is UP (use show interface

command)

 Assure to start one kind of multicast protocol on the interface

 Assure the time of the timers of each router on the same network

segment is consistent; usually we recommend the default setting.
