Considering redundancy, getting as much bandwidth as possible and future QoS support, what is the best way to bond two T1's? I am currently running multilink because in the lab it behaved the way I wanted. I have two identical sites, one works fine and the other bounces up and down as soon as I introduce traffic. I only have one T1 plugged in until I can get the second installed. If I change my clock source from line to internal it goes down and stays down. The TAC says that I need the two T1's or the clocking will be messed up. If that is true then I do not have redundancy.
I have this problem too.
