Hi All!

I have some clients that have internet access by a linux machine (RH 
8.0) with a NAT. The machine has ip 192.168.0.21 and has connect to two 
adsl modem that have the follow ip: 192.168.0.1 and the other 192.168.0.2.
I need to switch automatically the linux machine kernel routing table 
when a adsl modem go down.

How can I configure my bird.conf to do this?

Best Regards,

Maurizio Paluan
