Hi Neependra,

Thanks for your help.

I have alreadly tried this and there are some problem with this setup.
It switches routes only when the physical network is down, ie when network
cable is unplugged or device is not reacheble .

If physical link is not down and if there is problem at ISP side then it
dosen't switches links.

I think this can be achived by a script which will continiously check if the
default route is alive, (by pinging to standard sites) if it gets no
response then it should automaticaly switch the links.

Any ideas on this???
I am working on it and hope to crack it soon. Any suggestions are welcome.

Thanks for your help
