Default Openbsd: Bgp ospf conditional redistribute default

Hi,
I'm trying to distribute a default route to my intern network thought ospf, but still searching the way to do this with the short path...

Code:
BGP Provider A        BGP Provider B
       |                             |
       |                             |
    BGP A                      BGP B
       |                             |
-----------------------------------------------------...
       |                             |          | 
       |                             |          | 
    GW 1                        GW 3    GW 4
All BGP server have the full table of internet routing.
The BGP A and BGP B have a iBGP configured, and announce the x.y.0.0/20 network to providers.
The GWs and BGP A and BGP B have ospf daemon installed.
Gws announce the x.y.z.0/24 networks to all servers in the ospf.

In the beginning no default route was set for GWs.
I use the !route add -reject default 127.0.0.1 command for the BGPA and BGPB. So now a have two default route for the GWs.

Now if i cut down the bgp session between the BGPs A, the default gateway of the GW still is the BGPA. I means the transit is:
GW1 -> BGP A -> BGP B -> BGP provider B

I would like what the ospf announce the default route only if the bgp session is active.

I miss something ?
Anyone know how to do what ?


Best Regards.

Sorry Vincent... this forum is for Wood Working Routers.

Sometimes I wonder whether the world is being run by smart people who are putting us on
or by imbeciles who really mean it.
