should pay attention to the following issues:
To assure that physical connection is correct.
To assure the Protocol of Interface and Link is UP (use show interface command);
To assure PIM Protocol is enabled in Global Mode (use ipv6 pim multicast-routing )
Enable PIM-DM Protocol on the interface (use ipv6 pim dense-mode command)
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 PIM-DM can’t be
solved yet, then use debug commands such as debug pim please, and then copy
DEBUG information in 3 minutes and send toTechnology Service Center.
