Sam,
You use ip pim nbma-mode on any multipoint serial interface. It is used
so a spoke that doesn't want multicast traffic doesn't purge the traffic
from the whole interface and thus purging from the other spoke that requests
the multicast traffic. The command enables multicast on a per connected IP
basis rather than an exit interface basis.
