Re: how does the multicast source register with the local mroute

The multicast source only needs to register with the multicast router if it is also a receiver. Otherwise, it simply starts sending traffic to the multicast router which creates dynamic state based on received traffic.

Hope that helps - pls do rate the post if it does.

According to Cisco, "some reserved multicast ranges are excluded from being snooped by design" it will broadcast the traffic instead of "listening". check the multicast addressing. try changing the IP Range.
