Use the pim ipv6 hello-option neighbor-tracking command to disable join 
suppression, namely enable neighbor tracking, on the current interface.

Use the undo pim ipv6 hello-option neighbor-tracking command to enable 
join suppression.

By default, join suppression is enabled, namely neighbor tracking is disabled.
