Checking my notes from the time, parallel/fast boot was supposed to go into 11.1(8)CA, but I seem to recall it didn't make it. Good to know it's there now, but which version is this?
It certainly has been around for quite some time; all 11.1(13.5)CA and subsequent images have it, and probably quite a bit sooner. Perhaps this is unclear because you overstated the nature of the problem. Even with 11 slots and without this feature, it never took 30 minutes. I think the actual number was more like 30 to 60 seconds per VIP2. At least, that's my understanding. --jhawk who continues to think this is really not nanog-relevent crud and further, even if it would have been, this thread should have died, and we're all being socially irresponsibly by furthering it; insert cynicism here.
