Mark,
Can you also along with the information Bryan requested, check if you
see if auto-rp converged properly? By issuing a 'show ip pim rp
mapping' on each router.
Check the RPF information available with 'show ip rpf' on R3 of the
router that has the connectivity issues.

Mark,
R3 is the one that has the joins, but you say R3 cannot ping the
groups? Is this correct? Or did you mean R1?
Also, are they any other connections between these routers?
What does show ip pim mroute look like on R2 and R3 after trying to
ping from R1?

I have an rpf issue I am trying to resolve.
I have 3 routers ip multicast routing, ip pim sparse, Autorp and ip
pim autorp listener configured.
I can ping the igmp groups from r1 and r2 but I can not ping the
groups from r3. The groups are configured on r3. Looking at it again
I sometimes the pings will work from R1 and sometimes they do not.
r3 f0/1 was saying it's not an rfp interface. I added a mroute ong
r3 pointing to r2 and it did not do anything. I added an mroute
pointing to f0/1 on r3 and it did not do anything. Ip v4 pings to
all interfaces work fine, so no unicast routing issues.
r1, r2 and r3 and connected to each other via frame-relay. The fast
ethernets all go to different vlans.
