Hi
Directly coming to the point. Suppose I have 3 ethernet connections from 3 diff. ISPs. How can I make failover from one to another. Like suppose first fails second shud come up if second fails the 3rd shud takeover and restore 1st connection when it comes up.
Regards
Mangesh

More correctly - you need to first decide- do you need incoming access or outgoing access ?
And, do you have a fixed IP ?
for incoming access - you need a fixed IP and need to involve all the 3 ISPs by asking them to update their routing table to include a route to your IP/ IP subnet. If they hardwire the rules, then youve also got loadsharing on your incoming pipe.
lookup BGP on linux for configuring outgoing access - it isnt trivial, but is hasslefree once youre setup.

<snip> Be specific. What fails in your question ( Ethernet card or ISP connection ).
Ethernet Card level failover are build up in driver's itself.
ISP connection faiover can be done via any script also.

What you probably need to look at is iproute2. It has many features one of them being that u can manage links over multiple ISP's.
Using this you could bifercate different traffic over various isp interfaces, or you can have one active and other dormant. In the later case, as soon as one of link goes down the whole traffic shifts to other designated interface.
