BGP, OSPF and Routing

[Robert Sander]

Hi,

I have two BIRD routers in two locations connected to the same CIX-LAN.

Both establish BGP sessions to the route server of the CIX.

Both routers do OSPF on their internal interfaces and see each other
there (in area 0).

How do I prevent the following situation:

When I disable one of the BGP sessions to the route server the router
still has direct routes into the CIX LAN because it learned them via
OSPF from its partner.

I would like to see the routes pointing to the router that still has the
BGP sessions established (even if that means a hop more).

Is that even possible?
Do I really have to take down the interface to the CIX LAN?

Regards
