That is what I want. But is that what will happen if I order two GigE circuits from the same Telco who is using Juniper and advertise the same subnets into both with BGP? I also do not want out of order packets so it would need to be per-connection load balancing rather then per-packet. I do not care, at this point, that a single connection cannot exceed 1gbps. >>> Not sure what’s hard about the load balancing?
