Well, I talked to my brother-in-law, who also studied the same
materials, etc as I did, and he recalled the same thing.... I did
verify as Dennis did, and it shows up with an AD of 1, but I also agree
with Chuck that this may be a newer IOS "feature". I didn't have time
while @ work, but we have a boatload of 2500's with 11.x IOS so I can
try it there too.... I even remember part of the 'theory' behind this
was that making a static route out of an interface was more 'reliable'
than sending to a next-hop IP (which may or may not be up even if the
local interface it up), so they made statics using exit interface an AD
of 0, and statics using next-hop an AD of 1. Fun fun......

I thought Mike was correct when he wrote that. But then I looked on CCO
and didn't see that caveat there anymore. Either Mike and I both read
and studied the same wrong info, or maybe Cisco changed it in 12.x?
Guess I'll check the 11.3 docs.
