Update from 11.3.  I don't know how old that is, but PIM was a
 moving target for a really long time.  There are all kinds of
 differences, although in the topology you show here, perhaps
 they wouldn't show.

Do you have the 7206 configured as the RP?

I see you have a static RP on the 4700, but I dn't see it on the
 7200.  Old IOS (11.3) might accept a PIM join and become the RP.
 Newer IOS won't accept a PIM join for a (*,G) unless it is
 specifically configured as an RP.
