Just came accross an interesting tip that would help you with this. From
page. 17 of Packet 3rd quarter, under the maintence section, you can use the
"default" command to remove blocks of configurations, like "default int fa
0/0" will remove all the interface config from that interface. Since you
didn't want to do a wr er and reload, you could just default everything
whcih is still faster than "no blah blah blah".
