Router A and Router B are an Autonomous System. Router B is the border
router. It should advertise itself as the route to the autonomous system,
but none of the internal routes.

Subject: RE: BGP4 implementation
Date: Tue, 5 Sep 2000 10:00:37 -0400
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.
