I have an ASR920 (17.6.5) with existing multicast streams on a BDI. On the same BDI I want to add another multicast sender (iperf2) but the multicast is not recoginzed and the RP is not informed about the Mcast stream. I have onboard interfaces that have active streams and sources on the same BDI. Is there anything special to this additional interface card in terms of multicast that I need to configure in order to get that running?
