RouterGod Celebrity Interview Series

Fabio on Cisco's IGRP Protocol

Welcome to another RouterGod celebrity interview.  Over the years we at RouterGod Online Magazine have interviewed many beautiful and alluring female celebrities on the subject of Cisco internetworking.  Yet our women readers constantly complain about the lack of eye candy for them.  We tried to placate them with our interview of Hank The Angry Drunken Dwarf but the complaints persisted.  So we contacted Fabio and he graciously agreed to an interview.  But who should interview Fabio?  We were at a loss until someone suggested network goddess

Priscilla Oppenheimer.  Author of such books as Top Down Network Design© and Advanced Particle Weapons For Dummies©, Priscilla Oppenheimer is also a much sought after guest speaker and technical instructor.  It is with great pride that we bring you this interview with Fabio on Cisco's Interior Gateway Routing Protocol:


Although us guys can't
understand it, women find Fabio
quite attractive.  Go figure.

Priscilla Oppenheimer

Fabio, wow, I hope you don't mind me saying so, but I would have never guessed that you were interested in routing protocols.

Fabio

Do not apologize my darling.  There are many things about Fabio that would surprise you.

Priscilla Oppenheimer

Well, let's get started, what is it about IGRP that got you interested in it?

Fabio

Oh my sweet, special little flower of womanhood, you are so impetuous, you want Fabio to share with you the intimate and private details of my relationship with a routing protocol, do you think Fabio is the type of brute who would kiss and tell?

Priscilla Oppenheimer

Good grief!  What on earth are you rambling about?  I asked you a simple $@#*% question!  Please, without all the sticky romantic hyperbole, tell us about IGRP!

Fabio

Oh, you are playing hard to get!  Fabio likes a woman with spirit!  Alright then, Fabio will say the words you want to hear.  Fabio will tell you about IGRP.  As you know, IGRP is a Distance Vector protocol.  I don't know how you Americans say it but in my country they say that a Distance Vector protocol spreads much gossip.

Priscilla Oppenheimer

Yes, we say "Routing by Rumor".

Fabio

Yes!  I can see you are a woman of the world!  A Distance Vector protocol simply gives a copy of it's routing table to it's neighbors, and they alter the metric to reflect the added cost and merge it with their own routing table.

Priscilla Oppenheimer

What sort of metric does IGRP use?

Fabio

Oh my Dear Priscilla, I will tell you.  IGRP uses a composite metric based on the lowest bandwidth along a route and the sum of the delay along the same route.  As you know, this is a much superior metric than RIPs metric, which is simply, hhmmmmmm, how do you say? a quantity of leaps...

Priscilla Oppenheimer

We would call RIPs metric a hop count.  What else makes IGRP better than RIP?

Fabio

Well, my inquisitive and sweet bundle of joy, RIP only allows a network diameter of 15 hops, where IGRP can support a network diameter of up to 255 hops although 100 is the default.

Priscilla Oppenheimer

How often does IGRP send routing update?  Rip sends them every 30 seconds.

Fabio

IGRP sends out updates every 90 seconds, and it uses triggered updates and hold down timers, just like RIP.  These features speed up convergence.

Priscilla Oppenheimer

Is IGRP a published standard, like RIP?  RIP is described in RFC 1058.

Fabio

IGRP was created by Cisco, it only runs on Cisco routers.  There is no RFC as it was never submitted to the general public for comment.  Let me tell you what makes Cisco so special.  Would you like to hear why Cisco is so special my little dove?

Priscilla Oppenheimer

Alright, Fabio, if you insist.

Fabio

Cisco is a lot like Fabio, beautiful and one of a kind.  Cisco invented the router.  Soon thereafter many imitators began selling routers but Cisco was the first, just like Fabio was the first.  Cisco is the only company that actually created their own routing protocols like IGRP and EIGRP.  No other company can say that.  Not HP, not 3 Com, not Juniper, no one.  Cisco is head and shoulders above the competition, just like Fabio.

Priscilla Oppenheimer

How do you configure IGRP on a Cisco router?

Fabio

It is very easy my dear, Fabio will show you.  Put your hands on the keyboard and Fabio will place his hands on top of yours.  Then I will teach you.  I will be gentle, I will show you the ways of the Command Line Interface, you have nothing to fear, Fabio will protect you.

Fabio got his start posing for the covers of
romance novels.  Romance novels are actually
pornography for women.  Since there are no
lewd, explicit photos, romance novels
are all but unknown to men.


Fabio and Priscilla embrace.

"He's not the sharpest pencil in the box, but
he's good looking and seems to be a nice guy"
----Priscilla

 

Priscilla Oppenheimer

Look, Casanova, if you so much as touch my hands, I will slap you so hard your kids will be dizzy!  Simply telling me the commands will be sufficient.

Fabio

You are truly a hot blooded woman, Fabio approves!  Very well.  Fabio will tell you what you need to hear.  Fabio knows what a woman needs to hear.  Come close, I will whisper in your ear, I will say things no man has ever said to you.  Perhaps now you are feeling light headed.  Perhaps soon you will swoon and fall into a love induced delirium...

Priscilla Oppenheimer

You don't know the commands!  Ha!  I caught you!  You are vamping for time, hoping I will forget the question!  Isn't that right, Fabio?!?!  You don't have a clue, do you?  Every CCNA on the planet knows the commands, but you don't, do you?

Fabio (eyes cast downward)

Do not be cross.  Do not be disappointed in Fabio.  Fabio is only a man, he cannot bear to think that he has let a woman down.  My heart is heavy and filled with remorse.  Fabio remembers when love filled our happy hearts.  All that is left for Fabio is to end it all, perhaps I will jump into a river, perhaps I will overdose on sleeping pills and dream of our time together.  Yes my Priscilla, remember me when I am gone...

Priscilla Oppenheimer

You're doing it again!  As soon as you can't answer a question, you launch into that romance novel mumbo jumbo!  Please, give it a rest.  I will tell you the commands to configure IGRP.  First from Global Config mode you enter the command router igrp followed by an autonomous system number, one will do.  Then you have to advertise your networks using the network command, just like you do with RIP.

Fabio

Fabio must confess that he forget all the commands you taught him during the practice interview, how do you verify that IGRP is working?

Priscilla Oppenheimer

Examine the routing table using the command show ip route, also look for the proper configuration by using the command show running-config.  You can also do some debugging and also use the command show ip interface brief to make sure your interfaces are UP and UP.

Fabio

Fabio says "Thank you".

Priscilla Oppenheimer

Priscilla says "You're welcome".
