Yes, but thus thread is discussing dense mode where there are no join messages.

I thought that ip pim nbma-mode is suppose to solve this problem, since it allows the multiple join messages over the frame. So, doesn't it work if you configure ip nbma and sparse at the hub along with sparse-dense mode at the spokes?

I don't have a link offhand, some time using google will probably find
one somewhere, but I think the concept is straightforward enough to lab
up and get some experience with. Consider this.
R1---R2

R3
In this setup R1 is the hub, using a multipoint frame interface and all
the directly connected interfaces are on the same subnet.
Multicast will not normally be sent out the interface it was received
on, so that is a challenge for R2 to R3 communication. So create a
tunnel between R2 and R3 and enable ip pim dense mode on both ends. As
long as you have IP conectivity between the addresses used to create the
tunnel by the IGP, you should be able to get it to work.

Hi Chris,
Would you mind to provide any link to talk about this with examples?

get dense mode (or sparse-dense mode) to work between a sender on one
frame relay spoke and a receiver on another frame relay spoke in the
same subnet?

for sparse mode, there are no joins in dense.
The command reference is great at explaining things like this

the ip pim nbma-mode command on a multipoint frame-relay interface but
it generates an error message saying that PIM nbma-mode is not
recommended for dense mode or sparse-dense mode?
Why is this?
