Stuff to go over again
This is what I will be doing next, just to recap then ts off to the land of the big bad assessor lab!
MST – not hard, but I dont get much exposure to this so I will do it again
DAI/DHCP Snooping – not something I do much either
BGP – Conditional advertisement, aggreration with leaking specific routes, communities and regexp (is there anything else left in BGP? 
)
Multicast – not difficult, but not exposed that much to it.
