Yes. I am doing something similar in my lab and if you put 'redistribute
ospf <pid>' under bgp, it will take the command and return no errors until
you try to find those routes somewhere else in your bgp domain.

I also found that the routes from EIGRP into OSPF did show up in BGP by just
redistributing OSPF. I did not need to redist both.

Finally, if you have 'redistribute connected' in your OSPF, connected routes
will be seen thru ospf but will not redistrib into BGP.

But, what is the default in this case?, don't diustribute anything?
