At this point, it think it would be good to mention that (IMHO) it's best to
use the LoopBack interface for ip unnumbered because it can never go
down......
In the config snipet you gave, your Serial0 couldn't communicate if
FastEthernet0 went down.
I do believe that with some version of 12.x, however, Cisco has made it so
that even if the interface goes down, the unnumbered interface can still use
it's IP, so be sure to check your IOS version, and see if that's the
case...... But, that's just another good reason to use LoopBack because
then you don't have to worry about that...... =)
