Your multicast table shows that you have no RPF neighbors. Thats why it's
failing. Now to figure out why you have no RPF neighbors on your mcast routes.
I'd take a look at your interfaces involved to make sure they all have the
appropriate PIM statements and check "sho ip pim neighbors".

See if this helps: BTW, I have completely erased this router and reloaded it
with minimal config but the problem persists.

That does look right, what does your mcast routing table look like?? sho ip

Thanks for your response Max,
The route is to 235.23 so it appears correct to me.

Look at your debug a little closer. When you do a "sho ip route 192.0.0.23",
what does the next hop interface show up as??
