That is a very good question, but that would take way more space than this forum offers. A good router tutorial, which covers the configuration from the IOS command-line interface can also be found here
You should check out Cisco's page on EIGRP (link
) or Petri's Blog about configuring EIGRP (link
), but if routing protocols are in general a new thing for you, you will be better advised to get a book that covers all protocols, otherwise this might not make any sense to you.
Look for this:CCNA - Cisco Certified Network Associate Study Guide by Todd Lammle, Publisher: Sybex
You can get it at amazon and it costs you only 20$ (used) or 30$ new including shipping. Here is a link
If you have specific questions, I'm happy to help, but in the book it's already more than 60 pages on IRGP/EIGRP alone, so I don't really want to type that all up, plus you would need some general information as well.
