Does anyone know how to bond or load balance two cable modems with a Cisco router? I saw an article that can load balance with NAT, but I didn't know if that just splits the connections. Is there a way to utilize both connects? IE, if I normal get a speed test of around 10MB down, I could bond them and get a connection of around 20MB? I saw cable modem WAN load balancers, but didn't know what it was actually doing. I would like to do it with Cisco router of layer 3 switch if possible.
