Setting up loopback interfaces on Cicso routers

I want to set up loopback interfaces on my Cisco routers but have not been able to find precise information on how to do this. Can you suggest where I might find good info to get me started?

In order to set a loopback interface on you have to go into configuration mode and type the command: 'interface loopback0'. Next you would enter in the ip address by using the command: 'ip address (address) (subnet mask)'. Then you would exit out of configuration mode and save by entering the command: 'write memory'.

Go to www.cisco.com to find good information on how to configure a router. A good beginner's book to read for configuring a router is "Cisco Routers 24 Seven" by Andrew Hamilton.
