Aggregate bandwidth at a threshold on IOS Router

Hi All,


I have a 1811 that is used to failover between 2 different WAN providers. One Cable and the other DSL - works well. I now want to aggregate the available bandwidth from these two and use all that is available. I want to allow a bandwidth threshold of 80% with the primary link and start to send all new requests down the secondary link till I saturate all available bandwidth. Can IOS do this?

For outbound, what you describe might be possible using OER or PfR if either is supported on the 1811.

Yeah, I guess I should clarify, I have done this on 1841s. Never done it on an 1811 before. Plus, with that, you would have to vlan off a switch, unless you put in another ethernet module for it. The 1841s do work well, but I will say I had to upgrade the IOS to support object tracking, maybe it was SPServices (cant remember right off). Either way, its really cool.
