Hi, thanks for uploading the videos. Iv just graduated and pursuing the ccna training.

By the way, your system responds very quickly each time you type in an it ENTER. Though the GNS is a CPU intensive software, there is no lag in the CLI.
What is the configuration of your laptop???

How are the routers connected. Not Serial, No Switches. What if my router only has one Ethernet interface, how can one use this video as a beginner?

it shows 2 values marked with * sign for potentially good. one is 58 and other 55, which is best?

[soumiksen]

and another thing, about the loopback addressing scheme. For example i choose the loopback address 1.1.1.1 So when you create the loopback, why the subnet is 255.255.255.0 Why dont we take 255.255.255.XXX where XXX could be 254, because there is only one host

arent those 3 routers connected via cross over cables

@routergods i dint get your point about idlePC

[routergods]

@9887962543 - Have you set the idlePC in GNS3?

[deepakkumar-tixu]

you haven't tell why they are used basically

[routergods]

@9887962543 You can make your subnet anything you want as long as it doesn't conflict with other IP addresses.
