Hi there,

What you are asking about is called Mutual redistribution and its doable but it can cause routing loops so you must take care:

Mutual redistribution between protocols should be done very carefully and in a controlled manner. Incorrect configuration could lead to potential looping of routing information. A rule of thumb for mutual redistribution is not to allow information learned from a protocol to be injected back into the same protocol. (You can use any filtering method).

here you are also a nice post from the forum:
