Hi Brant,
Well... I would think its not required too (if the router is not
configured to bridge, etc..), but Cisco's doc recommended it (just
do a search for router any you'll hit the NOTE) :-
http://www.cisco.com/en/US/products/hw/switches/ps700/products_tech_note09186a00800b1500.shtml
In fact, even IE's workbook Lab 1 task 1.7 recommended not turning on
portfast for ports connected to routers.
Of course this is not a DO-IT OR DIE/FAIL kinda situation but I just
want to hear some of your views on this.
Thanks.
