David,
I think you are right on with this one. I would also check the sh
ip ospf and sh ip bgp to make sure the RIDs are the same, but I would
also put the redistribute ospf 1 match internal external 1 external 2
command.

If I remembered correctly, OSPF will not redistribute external route
into
BGP by default. Could this be the reason why?

When redistributing ospf into BGP I belive you have
the same router-id to verify (hard code would be best)
the router ID's on both BGP and OSPF for
redistribution to work.
I would say that if router 2 sees an OSPF route and
you redistribute it into BGP then you should be good
to go (assuming you have similar router-id's).
Also, R3 (if syncronization is enabled and R2/R3 are
running IBGP) then R3 would see the route in it's ibgp
table ("show ip bgp") but would not install it "show
ip route bgp" until you disable syncronization or
somehow get it to R3 (ospf...)
HTH.
