Kevin,
I had seen that and wondered about that myself a while back. I never found
any problems using unnumbered interfaces even after a fair amount of
testing.
I still can't explain why CCO says that but it seems not to be true.
BTW, there are lots of mistakes on the doc-cd so maybe this is just another
one or maybe this is one of those things that used to be true but the doc's
were never updated. <shrug??>

Subject: Unnumbered warning ?
I saw the following warning about unnumbered interfaces on CCO:
"Using an unnumbered serial line between different major networks requires
special care. If, at each end
of the link, different major networks are assigned to the interfaces you
specified as unnumbered, any routing
protocols running across the serial line should be configured to not
advertise subnet information."

I can not figure out why ?
