RouterA is using OSPF,not BGP, and it has a direct connection to RouterB, which is running BGP and OSPF. What I'm concerned about is the other AS clouds that connect to RouterB would see my network in RouterB's BGP updates and thereby using the link between RouterA & B to get to my RotuerA network. That is what I'm trying to avoid. As you can tell, I'm still very new to BGP. Any suggestions of implementing this "firewall-like" stuff is gladly appreciated.

Are all these routers in different AS's? Same AS?
Does routerA have only 1 transit connection, and thats routerB?
If so, why even run BGP?
There are ways to do what you want, depending on the above.
