How to create loopback interface in cisco packet trace

How to create loopback interface in cisco packet trace 1.       Let me tell you what is need of loopback over network. In each router there are many interfaces like ethernet, fastEthernet, GigabitEthernet, console. All interfaces have different different IPs. It is difficult to manage whole network for network administrator. So network administrator creates loopback IP for each devices for his or her comfort. 2.       So lets how do we create Loopback IP. We are taking 2 routers and one PC which are connected through cross over cable. Assign IP to each connect port. As given in the picture below. 3.       For example I am going to create loopback IP for router0 192.168.5.1 and for router1 192.168.10.1 . Loopback ID is required for creation of interface. We can put as per our choice. As I put loopback 1. Same we will do for Router0. 4.       Loopback has been created. For testing we need to login by telnet so that we can check loopback is accessible from remote location. Below are commands to create telnet. Router#config t Router(config)#line vty 0 15 Router(config-line)#pass Router(config-line)#password cisco Router(config-line)#login Router(config-line)#exit Router(config)# Router(config)#ena Router(config)#enable secret cisco Router(config)# Router(config)# Router(config)# Router(config)#exit Router# 5.      Now we will check it from PC>Desktop>Command Prompt 6.      It is accessible from remote location. By loopback IP 192.168.5.1 user can access router. He or she can configure any thing on device. Instead of keeping all IPs of each port, one loopback IP is good. 7.      Kindly put comment on comment box for any concern or suggestion. \
