I dont' know a whole lot about redundant internet links, different types of routing, spanning-tree protocol, etc. but I figured it would be super cool to have a backup internet connection at my house. I have asked the Network Architect at work about it, but every time I do, he says a bunch of things, but doesn't say how to do it. I don't think he really knows how to do it without several thousand dollars worth of high-end hardware. So I'd be able to impress the shit out of him that I could do for <$200 what he needs a ton of cash for -- I'm not even sure that he has it at his house. So here's what I'm figuring is the best thing to do: Sorry for the shitty drawing, I'm using gimp on a laptop -- not the best combo. What the illustration shows is that my two routers are connected to separate internet pipes. Then they connect to each other (the blue line), and they connect to clients. If one internet pipe dies, the traffic should get routed through the alternate pipe. I know that this is possible with the Spanning-Tree Protocol. I also know that the Linksys devices make STP traffic (I've seen it in Ethereal). So does anybody know if they also take advantage of the STP traffic to reconfigure for a down internet connection? If so, does anybody have something like this running? How do you have it configured? Does anybody have a wireless access point around them and a couple of WRTs they want to try this out with? I don't have any wireless access points around me or I'd try it with my cable modem and the AP. This sounds like too cool of an idea to NOT try out!
