In future, we are likely to have a situation where the DR is not the
RP on the SM side. The documentation for igmp interface X static..
suggests it does not cause the router to send a PIM Join and so if the
SM/DM border wasn't on the RP, the traffic may not get propagated.

Is there a way around this problem?
