Hi Kami,
It will depend on when they get marked. Generally this is streight away, sometimes it is not. You must work on the assumption that it will be. I reloaded at lunchtime (then my first job back was to re-verify everything), and then when I'd finished the first run thought the paper. Again, you then need to re-verify it all..
Any config you do should assume that it will be reloaded, so make sure your OSPF DR's are clearly defined with priority (and non-DR's set to priority 0 etc) and as apd123 said have all your router-id's set..
Cheers
Dan
