Group,
I was looking at some documents at CCO, and noticed that sometimes their
examples use /32 IP address like :
interface loopback 0
ip address 172.16.254.3 255.255.255.255
Can someone help me to understand reason behind in using this type of
address in the configuration ?

1. This is a loopback interface. It is always up. Which means, if you
statically
or dynamically make this /32 host route accessible via anywhere in the
network,
you can connect via IP to this address instead of each regular interface
(serial and ethernet interfaces go down).

Though I do not have an in-depth knowledge in loopback interface. I would
like to add on a bit of my experience working on it.
I have tried to configure a loopback interface for NAT kind of config (For
Internet access ) with the interface as ip nat outside. It did not work.
Eventually, I have to
