Spoke to spoke multicast is not allowed.
If you have sparse-mode configured ip pim nbma-mode solves this issue.

Subject: Multicast DM/SM on NBMA hub-and-spoke topology
Hi Multicast experts,
Can someone clarify how the Dense & sparse mode work on a NBMA /
hub-and-spokes setup?
1. Is dense multicast traffic allowed between spokes?
2. Is sparse multicast traffic allowed between spokes?
3. What does the "ip pim nbma" command on hub multipoint interface solve
here?
If you can pint to a link to clarify these, it will be much appreciated.
Thank you for your replies.
