Receiver joins FF0E::1 group
R5 (RP) has the following:

Reply to request 0 received from 2001:192:166:1::7, 40 ms
Success rate is 100 percent (1/1), round-trip min/avg/max = 1/1/1 ms
My question is why R1 fails to send ping packets .
Any help is appreciated !!

Do you have "ipv6 multicast-routing" enabled on the sender as well by any chance? If so, can you disable it and do the test once again.

I'm glad it fixed it. The issue is that the IOS is used as a host in your topology. When you configure it with "ipv6 multicast-rounting", you basically use it as a router rather than a host from the PIM point of view and this will cause all kind of issues.

I do have ipv6 multicast-routing on Sender.
I will remove it.
