Daniel,
The short answer is no you can't.
When redistributing from one protocol to another the routes have to have
been learnt on that router by the source protocol or by a network statement
on that router. The other check that is made is that the route has to be in
the ip routing table from the source protocol as well.
regards
Nigel
