I haven't seen the lab, either, but how did you perform the filtering of AS65000? When I read your post I was thinking of the neighbor remove-private-as command. That should allow R3's loopback network to propagate, just that R1 won't see the 65000 AS. Feel free to post your configs and anything else relevant, I'll take a look.
