We have two diff. ISP connections, using three old Cisco 2500 and 2600 routers — one for each ISP and a third as the loadbalancer behind the two edge routers. It has worked quite well except that
1) it doesn’t detect brown-outs and high
latency
2) it doesn’t detect a failed link further upstream inside a carrier network.
I am looking for a smarter, low-cost, hardware solution right now. Beside buying higher-end Cisco and implementing their more complex
protocols, I am also considering Linksys RV-082, Astro Corp Powerlink Pro50, Zyxel Zywall 70, xincom XC-DPG502 Twin WAN Router, Alvaco
OPTIQROUTE 2120. Some of these are 200-300 bucks and some at around 1000.
Does anyone has any experience with these devices? How effective is your device in detecting brown-outs and remote link failures? How reliabe is your device?
Any comment will be greated appreciated!
