Sounds pretty good - hows your power draw on that thing? Why'd you pick Bird in this case?
this a standard sr that's moderately busy but not exactly slammed, I'm be impressed if you could triple that at full tilt. #show environment power Power Input Output Output Supply Model Capacity Current Current Power Status ------- -------------------- --------- -------- -------- -------- ------------- 1 PWR-500AC-R 500W 0.35A 5.27A 62.8W Ok 2 PWR-500AC-R 500W 0.32A 4.81A 56.4W Ok Total -- 1000W -- -- 119.1W -- bird had memory footprint going with it as well as some local modification and we hacked addpath into it a few years ago. filtering poilcy is something we programmatically generate and interact with via agents so a traditional style monolithic config isn't that useful.
