GNS3 Lab & Exercise: GNS3-Labs – BGP & EIGRP Case Study 4

Written by LBSources from on July 6th, 2010 | 28 Comments

Hello All! Hope your weekend and holiday has been a great one!

Here is another one of the final Cisco Network Academy labs. This one involves BGP and EIGRP. A lot of good tasks in this case scenario. I wish that they would have had many more lab scenarios since they are exactly whats on the lab. There definitely needs to be a new lab book developed – Maybe I’ll create one? ;) Kidding!

Anyway … Onto the lab!

This is a lab from the Cisco Networking Academy Lab Portfolio.

CCNP Building Scalable Internetworks (BSCI 642-901) Lab Portfolio (Cisco Networking Academy)

Routers Used:3640


Feature of Topology: EIGRP, BGP, eBGP, Full Mesh iBGP, Summarization, MED, Local-Preference


Lab Objectives: Plan, design, and implement the International Travel Agency (ITA) core network
as well as the Travel Data Providers (TDP) network and allow the networks to
communicate via BGP. Verify that all implementations are operational and
functional according to guidelines.

Cheers and Happy Labbing!

I perform all of these labs on my own using my own knowledge and experience (warning and disclaimer). They may very well be implemented differently than a method you might choose. So long as it meets the requirements and works, essentially it’s acceptable (In my feeble opinion). But if you notice a terribly or complicated method used by me to achieve the goals and you feel yours is much easier, makes sense or is the standard; please do share – I’m always open to learning :)

    I wanted to point out that some of the references you have here are for Case Study 3 and some for Case Study 4.

    Also, I’ve been following along for awhile. I’m currently still working on my CCNA but find your labs very useful in understanding real world environments.

  2. avatar LBSources

    @Justin.. Yes that was my fault – It’s really lab scenario 4.. Lab scenario 3 is an OSPF lab that I’ll be posting shortly. Glad to you’re finding them useful. As I said before – I’ll be creating many of my own scenarios and posting them as well..

    Hello on GNS3 web site it has the following statement
    “users have to provide their own IOS/IPS/PIX/ASA/JunOS to use with GNS3″
    I was wondering if you know a good web site where I can obtain the images I need for each of the devices?

    Thank you for your assistance on this matter.

    Best Regards,

    I know my post here seems irrelevant but i want know is there any way i can practice MPLS lab on GNS3

    thanks for the lab!

    however.. cant ping the loopback interfaces on R4 (172.16.x.x subnet) from R2 as there is no route back to R2 from R4 since we only redistributed the loopback interfaces

    anyone else get this?

  6. avatar Krishna

    Hi Very thanks for the LAB.

    I also have the same issue from R2 i am no able to ping loopback interfaces on R4 (172.16.x.x subnet). I had also load your solution and checked but same result.
    At first sight i though it is due to “next-hop-self” as R1 and R3 will not change the next hop when it advertise the routes to its IBGP Peers so i changed “next-hop-self” on R1 and R3 but still no success.

    Nice lab. I enjoyed it a lot.
    When checking my own against the documented solution I noticed a few oddities in the solution configs provided. Also, the solution can be made more robust by adding an extra task:
    Fix the redundancy issue on R3 which occurrs when the link to R1 is down. You will find that it then routes traffic directly to AS65002 although there is still a path through its own AS.

    Please drop me an email and I will send you the solution configs that I ended up with.

    Keep up the good work!

    Under eigrp 65002 on R1 and R3, need to ‘redistibute connected’ into AS65001, to ping loopbacks from R2 to R4.

    Nice lab, I like it so much.
    Could you up BGP/OSPF Routing lab, it is CCNP advanced routing version 3.0′s case study 3. Could you help me, please

  10. avatar OmiBarbosa

    Good Lab, when smooth thru all the tasks until last one, but managed at the end. The labs are very helpful for my 642-902 studies. Thanx from Puerto Rico!

    did u give me stp leb which one is imp in exame

  12. avatar Alcides

    Hi I started doing this LAB task but I found something that make confusing. In LAB Objective said “…allow the networks to communicate via BGP…” and in task txt file said “Advertise the and networks in both EIGRP autonomous systems” so why do I need to advertise both if communication between network should be made through BGP?

    thanks for the job you guys doing , create pleasure to see this helpful community 

  17. avatar fryedfish

    I don't understand why adding  ‘redistibute connected’ into AS65001, to ping loopbacks from R2 to R4. makes that work….

    It is perfect time to make a few plans for the future and it is time to be
    happy. I have read this submit and if I may just I want to
    recommend you some fascinating issues or suggestions. Maybe you can write subsequent articles relating to

    Hi! I know this is kind of off topic but I was wondering if you knew where I could locate a captcha plugin
    for my comment form? I’m using the same blog platform as yours and I’m having problems
    finding one? Thanks a lot!

    yesterday i tried BGP routing on cisco packet tracer but it doesn't work. Are BGP must use GNS3?

  25. avatar Andrea

    I was wondering how does GNS3 compare to a real Cisco lab?  I was looking at the lab suggestions here and it seems pretty reasonable now days to build your own lab for about $500.  I am thinking since I learn better with hands on, it might be better for me to build my own lab.  I have also been reading that GNS3 does not do switching.  Is that correct?  Are there other things GNS can't do in a lab like TFTP stuff?
    Thanks for answering my newbie questions.

    Your method of telling the whole thing in this piece of writing is in fact good,
    all can effortlessly know it, Thanks a lot.
