Dave,
I agree totally with your statement, however, I don't understand why you say
that if you use ip unnumbered pointing to a LoopBack interface that
nullifies the point of using unnumbered (to save IPs). You can still use a
single IP address on a LoopBack not waste more by putting separate IPs on
each p-t-p link......
