I'm looking for some operational input on redback routers, specifically with regards to use for DSL aggregation over ATM of which so far I've found little information. My personal interaction with the Redback router has been pretty much nil other than being told what a nice provisioning system it has, and that at 70% utilization on the circuit it starts flaking. Now this could be a very specific situation in as much as poorly configured router (eg. lack of packet memory, munged config, etc) or it could be an issue with the hardware itself, which is of course why I'm trying to dig up something more than the standard 'our product really kicks butt' brochures from the vendor. All of this being said, if anyone has experience with this sort of situation or has pointers to better data I'd appreciate it.
