I agree that this command is awesome, I've used it for quite a while now. My
personal tip is that when you do this:
conf t
router ospf 100
net 10.0.0.0 0.0.0.255 area 0
then you should immediately do this:
do sho ip ospf int brief
and MAKE SURE you did what you think you did. It's an immediate reaction
with me, and one I highly recommend. It's surprising sometimes to see that
you've turned OSPF on an interface other than what you thought, or
potentially more interfaces than you thought. The real life saver comes when
you DIDN'T turn on OSPF on an interface you thought you would (maybe you're
on the wrong router, etc). Also, you should be paying attention to the
interface types and OSPF area's.
I also do this:
do sho ip eigrp int
for the exact same reason. Get used to doing these commands and it can save
you a lot of frustration. Also, this command will show you what AS your
interfaces are assigned to.
hth,
Dave
