Dear Sir,
I m working in a ISP as a network Engineer where all the servers are configured in RedHat Linux 9. We are using V-SAT and Local BTCL ie we have brought 40 mbps bandwidth from Goverment Telecom Service. And another 20 mbps from SinkTel singapur. Now at the present time what we are facing that most of the time Sub Marine Cable cut out in Bangladesh or other side of our cut out and it take 30 min or 2 hoour to up. Within this time we failed give back up of V-SAT instantly.


So please help me to know how can i configure this that when My Broadband link will be done then V-SAT link will be activate automatically within 4 seconds.

How can i do this??????????????????????????????????????
