Hi everyone, I have a question that kind of puzzles me and I hope it's a fundamental gap I'm missing that can quickly answer this. I have a client router receiving multicast traffic destined for its ethernet interface with an "igmp join-group" command on it. Thing is the multicast traffic is not incoming on its RPF interface, yet it's still working. I've done an extended ping on the source to verify I'm choosing the source address. I'm running sparse mode and I can see the mpacket count increase normally on the RP-tree for that (*,G) entry on the client. I do a debug ip mpacket on the client router to verify the source is not coming in on it's RPF interface. Shouldn't this be failing and dropping?
thanks, Dale
