Actually I just take one step further on one of my previous questions. Christopher Gatlin was helping me on that one I hope he can shed me some lights on this one as well.
In the diagram the f0/0 is the WAN connection to the Internet and the bandwidth is 30mbps. I have 3 internal networks A, B and C. They are all on public IPs so there is no NAT/PAT. Is it possible to cerate bandwidth pool (download direction) of 30mbps and share it among the 3 physical interfaces f0/1, f0/0/0 and f0/0/1? I want to gurantee 10mbps per link when the bandwidth is fully utilized but each link can still use up to 30mbps when another two links are idle.
