It is confusing when labs are referenced that most people will not have.
Iy would be much more productive if we concentrated on the concepts
involved.
During mutual redistribution between two routing protocols, the use of
route maps will keep each protocol from advertising the other protocol's
routes as their own.
A simple example:
Redistribute RIP into OSPF and use a route map to ensure that you ONLY
redistribute networks that are of the RIP domain.
Redistribute OSPF into RIP and use a route map to ensure that you ONLY
redistribute networks that are of the OSPF domain.
This practice will keep you out of trouble in many situations not just
physical loops. Also, keep an eye on administrative distance on the border
routers this can present problems to efficient route determination. I
would recommend the TCP/IP Volume 1 book by Doyle - the section on
redistribution covers this well. This is a book that everyone pursuing the
CCIE should have in their library.
I somewhat question $650.00 practice labs that consist of nothing more than
Visio's, a scenario and the configs. These labs require a lot of
equipment and will drive most people to their online lab to do the
scenarios - a very expensive solution. They provide no information to
complete the labs you will need to go elsewhere for that.
Look at the labs on fatkid.com. They approach individual topics and
provide good explanations. They are also FREE and his lab time is quite
reasonable. They also provide much more information on the configurations
and hence provide more of a learning experience. Most home labs can
accommodate these scenarios.
Remember there really is no quick solution to this game. Time will vary
depending on each person's time, experience and exposure but you will need
to understand each of the topics before you will pass the lab.
Now go read that IOS configuration guide! It's all you get in the lab.
