Learning by Doing: CISCO Certified Network ... - SCN Research

Supplemental Lab or Challenge Activity:
1. What is the “Variance” command and how does it relate to IGRP?
2. Repeat this lab using a class “B” IP addressing scheme.
3. Repeat this lab using a class “C” IP addressing scheme.
So What Did I Learn Here?
In this lab you have learned how to statically and dynamically manipulate your metrics to
achieve traffic flow in the manner you desire. Watch out for the “variance” command
when you are studying for your test. This is a good “one-line wonder” question—the
information only appears once, but you are still expected to know it anyway. In the next
lab you will learn more about that autonomous number thing-a-ma-jiggie. Don’t erase
your configurations…we will use the same one for the next lab.
Guest Router Name Derivation
In 1969 Dennis Ritchie and Ken Thompson invented the UNIX operating System. If they
only knew then what they were doing…creating software that would help put a man on
the moon, transmit pictures back from Mars, and the solar system…oh, yeah…and give a
green light to hackers everywhere. Nobody said anything was perfect.
