I see both on my GSR in NYC (199.109.32.35 is my vic), but don't appear to 
have a multicast route for 192.80.43.21, and that's preventing me from seeing 
it at my Juniper in NYC, which is what my local router connects to. IIRC, the 
GSR will use unicast BGP routes for RPF, so it is happy, but the Juniper 
won't. I also don't have a multicast route for the source. . .
