The first three things to do…
… when you are a working on a training lab .
1st : Hostname
You are working with severals routers, and you got one window per router… by default the hostname is Router , you can modify it with the following command
Router(config)#hostname backbone backbone(config)#
the command hostname affects the hostname of the router, the way the others will see it, and affects the prompt too.
You can change it while keeping the hostname with
backbone(config)#prompt MadRouter Madrouter(config)#
2nd : the dynamic resolution name
Usually, in a lab, you’re not working with DNS service and if you are making a mistake on an IOS keyword, the mad router will automaticaly consider it as a try to a telnet session and you will lose precious seconds.
To keep your precious time, disable the dynamic resolution name with this command :
MadRouter(config)#no ip domain-lookup
3rd : interface’s descriptions
Keep an eye on this, it will be more easier to troubleshot your lab by knowing who’s connected to who.
MadRouter(config-if)#description From backbone to Lab_A
