I was just wondering why you would waste a physical int. for a loopback? You
can create logical interfaces with the "int Loopback0" and so on. So why
would you take up a serial int unless you were using subinterfaces? I'm not
trying to be smart. I really want to know what or why this would be used
instead of logical int's. Thanks group.

You must be in the priv mode not user mode to put the router in loopback.
Router#
Router#conf ter ( hit enter )
Router(config)#int s0 ( hit enter )
Router(config-if)#LOOPBACK (hit enter )
Router(config-if)#end (hit enter )
Router#sho int s0 ( you will now see the serial interface in loopback)
To remove the loopback from the serial interface just reload the router or
do this:
Router#
Router#conf ter ( hit enter )
Router(config)#int s0 ( hit enter )
Router(config-if)#NO LOOPBACK (hit enter )
Router(config-if)#end (hit enter )
Router#sho int s0 ( you will now see the serial interface out of the
loopback)
