Logical steps to configure Cisco routers

This is just a technical note to myself actually and anyone who might find it useful…

As I have done the unexpected and now preparing for my CCNA certification (I’ll explain in another post soon), I tend to go with the approach that if I want to learn something, I should teach it to others.. So this post is part of this approach…

In easy steps, if you want to configure new Cisco router form the beginning, you should follow this approach:

  1. Configure router general settings
    1. Hostname, clock, terminal history size, DNS settings (name, IP, domain name)
    2. RSA key generation
    3. SSH settings
    4. services password encryption command
  2. Create enable secret, and create yourself a username
  3. Configure interfaces
  4. Configure whatever routing protocols/static routes you have

And this should be it, nothing complicated if you know your scenario and setup, and most important, you understand the logic the network is going to work with as all networks are just logical paths and flows (keeping the maths part aside..)
