Is there a way to have a router with an ethernet connection to two ISP's (and an inside interface of course) fail over from one ISP to the other when traffic stops flowing on the first one?
- Neither ISP shares it's routing table. (it's not an option so don't suggest it)
- Neither interface that faces the ISP's will go down (both ethernets attached to a switch)
I was thinking of something with a route-map to a known "pingable" address - force it out primary ISP interface - but how do you make it fail-over to the backup ISP.
Of course I could write a script that runs in conjunction with the route-map, but I'd really like to keep it on the router.
