Could you also post your 'show ip mroute' from R6 and the configuration on
R6. I assume you configured the static RP address?
Why it sends out on both interfaces is not really clear to me, but it
shouldn't be a problem, because at least one of the packets gets send out
well. You don't need a mroute here, but somehow it seems that your multicast
routing table is not really as it's supposed to.
