Yes and they are PIM neighbors.

Here is a show ip mroute from each if that helps:

Do you have pim sparse-den mode enable on all the FR interfaces? Are they
all neighbored up?

I am trying to set up the Auto-RP scenario.

The connection looks like this:

R2----(FR)------R3-------(FR)-------R5

R3 has separate physical interfaces for each frame relay connection.

R3 is set up as the only C-RP

R2 is setup as the mapping agent

R5 has a static join configured on it's E0/0 interface for group
226.26.26.26

My problem is that R5 does not receive the RP mapping announcement from R2.
I have a feeling this has to do with some multicast limitation of Frame
Relay, but I can't figure out what. I have tried enabling PIM NBMA-mode on
all of the interfaces.

If I configure R5 with a static RP address of R3, then everything works
fine. (i.e. I can ping the multicast group from Fa0/0 of R2)

Thanks
