warning: i've had one "high gravity steel reserve" over my quota. hit D now.
The issue I'm trying to address is to figure out how to extend the robustness that can be achieved with tuned IGP's with subsecond convergence across an exchange point without suffering a one to five minute delay blackholing packets.
why on god's earth would subsecond anything matter in a nonmilitary situation? are you willing to pay a cell tax AND a protocol complexity tax AND a device complexity tax to make this happen? do you know what that will do do your TCO and therefore your ROI? you want to pay this tax 100% of the time even though your error states will account for less than 0.001% of the time? you want to have the complexity as your most likely source of (false positive) error?
As far as I understand, this "complexity" just got added with Neighbor Discovery on IPv6.
if so, then, you misunderstand. -- Paul Vixie
