I have a question. But as a part of the queston I would like to ask that the responses consider that my objective here is to identify the narrowest (most consise) explanation/answer for the question posed. Which is:

In connecting two routers using IP interfaces; what are the minimal required actions in order for the innermost router interface to communicate through the outermost routers outermost interface.

Without the benifit of any dynamic routing protocols? ie.:


Router 1 F0/0 < ==== > Router 2 F0/0
<==== Router 1 F0/1 Router 2 F0/1 ===>



In other words to pass packets through Router 2's F0/1 interface through Router 1's F0/1 interface. What must be done to each router? No dynamic routing (protocols) are used.


I am working on my CCNA. I need to identify characteristics of the domain.

Well, the absolute easiest would be to enable a dynamic routing protocol and then everything should just work. Otherwise, you will have to setup total of 4 (I think for each router) static routes to have full communication from the F0/1 interfaces on both routers.

Maybe not even four - If you set up one static route on Router 1 for Router 2's F0/1 subnet, and a static route on Router 2 for Router 1's F0/1 subnet, it should fill in the direct-connected routes automagically.

You should research this yourself if you are studying for CCNA.

Yes, as I stated I am researching the problem.

My point is that this is basic routing---the foundation of CCNA. There are much more involved and difficult concepts jumping off from there. You should get the proper study materials instead of trying to Google. I would suggest an instructor-lead class(es), like the Cisco Academy, which is very inexpensive, relatively speaking, and the proper books, as well as real lab equipment (the right stuff), and instructions and labs on how to set up in different scenarios/topologies.

Amiel,

I am with Burt - the very least you want to do is pick up the Sybex CCNA Study Guide by Todd Lammel - runs about $30 on Amazon - then read it and do the labs!!!

Then when you have a question you will have some foundation under you as to how this all works and why.

Having taught at a Cisco Network Academy since 1999 - that is one of the BEST ideas - the Cisco Academy Program is taught world-wide - one of the best ways to learn CCNA!!!!

And setup a home lab ASAP and do hands on testing!!!

Just some thoughts! Good luck on your studies!!

Not exactly the answer that I was looking for... it was a kind of a trick question. Looking at the 'domain' itself as part of the answer.

SteveTheGeek answered the question concisely. The CCIE guide describes the answer exactly that way.

It is because the Cisco Study guide handles the answer(page 444 of the Cisco ICND1 study guide) to this in a somewhat vague manner (had to search to find it), that I was asking this question at all.

Curious to know how readily the answer can be had here.

To the CiscoGuy33, thank you.

I have learned that for me the 'Cybex' CCNA book is 'way better' than the Cisco Press books.

I had actually become convinced that I hated switches and routers... I have since learned that my annoyance and difficulty is entirely attributable to my using and depending on the CISCO Press book.

The Cybex book makes much more sense to my taste.

From my experience on any of the Ciscopress books, the first thing you have to do when you start reading them is go out to ciscopress.com and get the errata. I have found many mistakes and confusing points that were resolved once I read the errata.

Actually a default route in each router will do the trick. That's more concise than Steve's answer... :)

The directly connected links need no routing---they are directly connected.

R1=ip route 0.0.0.0 0.0.0.0 fa0/0
R2=ip route 0.0.0.0 0.0.0.0 fa0/0

You can do that and I don't even know your ip addressing scheme.

...as i was reading through this, i was just thinking that you could easily just configure default routes. I guess reading the book i got with the class i am taking is paying off.

Thanks for the thread....
