IGRP Config on a 2501

Unanswered Question
Mar 29th, 2007

have been studying for my ccna sice start of Feb this year - I have

a lab consisting of 1 x 2501 router and 2 x 2503 router and 2 1900

catalyst switches...I am using Todd Lammle's Sybex book as my text.

Currently on Chapter 5, and having configured RIP on the router, the

text advises to configure IGRP over this existing configuration - when

I list the available protocol's the list returned contains:






and one or two others

Could anyone advise why this Cisco 2501 router doesnt have the basic

(and cisco proprietary) protocol IGRP

and if possible, advise if and how I go about finding and loading this

type of protocol if it is at all possible?

My 3rd question is....

The text speaks about configuring the practice labs with more than the

3 basic routers which I have - for instance the one I am currently

looking at uses 3 x 2501 routers and 1 x 2621 router which I am not

able to configure because I dont have one. I was able to do the lab on

paper only due to this.

Anyone know the best way of connecting my 3 real life routers with say

a virtual termulation of a 2621 type router (as an example) as im sure

further into the book the config's the netwotrks become much much


Or am I best biting the bullet and getting the Bosom simulator for

such instances?

I have this problem too.

I will be happy to answer your first question. IGRP is out because it is replaced with Enhanced IGRP (eigrp). You can certainly downgrade your code and use IGRP.
