GNS3 Lab & Exercise: OSPF Case Study & Lab Scenario 3

Fri, 08/13/2010 - 13:14

How are we doing? So! As for me, I’ve beat the deadline for my CCNA expiration as well as the BSCI deadline! Wohoo! Very happy to say the least. Right now I’m working on SWITCH and hope to have this completed by the end of September..

There is a new site online that took the idea of this site (though they say they didn’t know this site existed) and is doing it 100 times better. If I could redo what I started here, I’d definitely do it a little differently today. But hey, at the time I was the only site. Anyway - the new GNS3 lab site dedicated and full of GNS3 labs is called GNS3-Vault and you can check it out at http://www.gns3vault.com .. Go check it out - they are doing a far better job with current labs than I can.

As for me, I’m studying very hard with the SWITCH studies and a new technical/study/personal blog at http://echoreplypackets.net. I’m sure I’ll be even more busy when I hit TSHOOT. I’m not saying I’m taking the site down or stopping labs, but this will end up becoming the site where I upload labs that I’ve used my own as well as labs that you guys contribute more than a lab supplying site.

GNS3 Vault is a great site! Go over and support it! Plenty of good labs.

Now onto the lab!

Scenario

The ITA needs its core network set up for OSPF with the following
specifications. Use the addressing scheme shown in the diagram.

  • Configure the OSPF backbone area on the Ethernet connection between R1and R5.
  • Configure the Frame Relay subnet as a point-to-multipoint network in area 100.
  • Configure R2’s loopback interfaces to be in area 200. Summarize this area with the most efficient summary.
  • Configure the Ethernet connection between R3 and R4 to be in area 300.
  • Add the loopback on R3 to area 300.
  • Make area 300 a totally NSSA area.
  • Redistribute the loopback networks on R4 that do not belong in any OSPF area.
  • Create virtual links as necessary for full connectivity.
  • Make sure that all loopback interfaces get advertised with the correct subnet mask.

Routers Used:3640 (Any type should be fine)

Petition Cisco for Educational IOS License!

Thu, 07/08/2010 - 02:54

So here is something that can very well take some time to come around the corner, but be here just like that and impact all of us. The new Cisco IOS (15.0) licensing methods are potentially putting our educational ability to study using GNS3/Dynamips at risk of coming to an end.

Here is a read from an article published by Dan Hughes on etherealmind.com

However this week marked the beginning of the end for this old friend, with the announcement of the supported hardware platforms for IOS 15.1, we see that only ISR and ISR2 routers are supported. For architectural reasons, it’s never been possible to emulate these platforms in dynamips, so we’ve reached a place where new IOS software won’t be usable in dynamips. We can run 12.4 on the existing range of platforms, and 15.0 on the 7200 platform, and thats it.

Today, it doesn’t really affect anything, unless you want to try the new hold music feature in 15.1, but over the months, as we head into 15.2 and 15.3, then the software we can run in dynamips will become too old to matter any more. Exam blueprints will move on, features we want to use will only exist in the new versions, we’ll update our production and test networks, and slowly, dynamips will become a thing of the past.

For those of us who have invested heavily in our own training and lab equipment, it won’t make a huge difference. Adding a few second hand 1841′s won’t cost a fortune, although will use a lot more power and cooling than the single dynamips box does. But for the ordinary CCNA and CCNP student, it’ll be too much to buy, too much room taken up, and too much power and noise. They can use remote labs, but they really don’t give the flexibility of your own kit.

So Greg Ferro put up a petetion off of an idea Wendel Odom came up with regarding an educational copy of IOS.

Do us all a favor and lets give it a shot and support and sign this electronic petition!

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

Tue, 07/06/2010 - 15:21

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.

GNS3 Lab & Exercise: EIGRP & OSPF Route Manipulation

Sat, 06/26/2010 - 17:00

So here is another lab I put together based on some studies and reading recently. I basically put together the scenario, so if it’s lacking conveying the scenario in a professional manner, I apologize

This is basically a simple route redistribution and route manipulation lab. Simple, but requires a few steps that will test your ability to adapt to an already deployed network while implementing a new routing protocol.

Hope you enjoy!

<a HREF=”http://ws.amazon.com/widgets/q?ServiceVersion=20070822&MarketPlace=US&ID=V20070822%2FUS%2Fgl0a-20%2F8010%2Fe41420d2-dd7a-4d3c-b296-72120d8c1cc0&Operation=NoScript” mce_HREF=”http://ws.amazon.com/widgets/q?ServiceVersion=20070822&MarketPlace=US&ID=V20070822%2FUS%2Fgl0a-20%2F8010%2Fe41420d2-dd7a-4d3c-b296-72120d8c1cc0&Operation=NoScript”>Amazon.com Widgets</a>

Scenario

Company Tapan wants to enable EIGRP AS 1 on R1, R2 and R3. They would like to connectivity between all routers and subnets with the exception of the loopback interface on R1. R3 should NOT be able to communicate with R1’s Loopback interface. Unfortunately Tapan cannot eliminate advertisement of R1’s Loopback interface due to other network dependecies on the other side of R1 (unseen here).

Additionally Tapan is planning to segment the networks between R1, R2 and R3 using OSPF. They would like 2 OSPF areas. The OSPF area between R1 and R2 will be the core (Area 0). The area between R2 and R3 will be Area 1.

Tapan has determined that they’d like to reach R1’s loopback via OPSF. Tapan would like that R1’s Loopback interface be reachable via OSPF ONLY.

Tapan has hired you as the network consultant to configure their required network scenario.

When R3 can communicate with R1’s Loopback using the scenario above, your job is done.

Because R1 is a bit inflexible, the IP and EIGRP configuration is already in place and CANNOT be changed. Only OSPF can be configured on R1 to R2.

Packet Pushers Podcasts - Listen In!!!

Tue, 06/22/2010 - 13:48

Ok - So if you’re not up yet on the Packet Pushers, you’re totally missing out on some good network discussion (usually) hosted by @Etherealmind, @ECBanks@Danhughes1234ie. The greatness about this podcast is it’s like sitting around and chatting it up with guys in your office or at a tech conference or on a project with other project team members - Thats how I see it at least

There is no other agenda to these podcasts except talking about the topics. There is no vendor target, no advertisements, no bias - though we are all Cisco minded They cover subjects such as DDoS, IOS Licensing concerns, Dynamips, MPLS basics, Technical interview tips, datacenter switching and the list goes on!

Overall it’s a great show to listen to and best of all, you may know all the guests on the show from Twitter. So it feels even more realistic since you may have tweeted with these folks for some time now.

I enjoy the show very much and I enjoy the guests even more! I recommend you check out the Packet Pushers Podcasts! Trust me, you will love it!

Cheers guys!

GNS3 Official Release: GNS3 0.7.2

Wed, 06/16/2010 - 17:26

Yesterday the GNS3 team released the latest version of GNS3 in which a virtual host was introduced among plenty of other new features and fixes.

The most anticipated addition is the virtual host capability. I’ve had the chance to debug this myself and I must say it works great! I’m kind of use to vpcs, but if you havent figured that out and would like to simulate hosts in GNS3, just download the new version and have fun!

Onto the release post..

Submitted by admin on Wed, 06/16/2010 - 01:01

GNS3 0.7.2 is released. Here is a list of the changes in this version:

* Lot of small fixes (relative paths, link removal, .net loading, Ethernet switch connection to a Cloud etc.)
* Qemuwrapper: random MAC address for devices
* NPE-G2 option for c7200 routers (need a specific and uncompressed IOS image and C7200-IO-2FE, C7200-IO-GE-E, PA-2FE-TX and PA-GE are unlikely to work)
* Simulated switches: daisy chaining support
* Improved directory selection for new projects
* New translations: Bulgarian, Italian and Ukrainian
* Frame Relay capture option for all serial links
* Dialog to display an Ethernet switch MAC address table

The following features will work only with a Dynamips version > 0.2.8 RC2 which has not been released yet:

* OIR (Online Insertion and Removal) for c3660 and c3745 (only NM-4T).
* JIT sharing support (saves memory).
* C7200-JC-PA Jacket Card support. Allow the use of a slot 7 for c7200 routers with NPE-G2.
* QinQ support for simulated Ethernet switches.
* Interfaces statistics (Packets in, Packets out, Bytes in, Bytes out). Displayed in node tooltips.

Also, we provide a small Qemu image of Microcore Linux 2.10, ready to be used in GNS3 and which includes ssh, iptables, iproute, tcpdump and IPv6 support. A small integrated simple host that supports pings is planified for the next release as well as some surprises

Not every translations have been updated so far but we will release a separate package containing the translation when there are up-to-date.

Thanks to all our translators, beta-testers, moderators and users which make GNS3 beter after each version.

Enjoy!

GNS3-Lab & Exercise - BGP Route Reflectors & Filters

Fri, 06/04/2010 - 12:03

Hope you are all doing well and celebrating the achievement of your CCNP or preparing to sit the exam very soon! Good luck.

Here goes the last of this BGP lab series - Next up? We’ll see! This lab will teach you how to configure a Route Reflector in BGP, you’ll learn how this type of configuration helps get around the BGP Split-Horizon rules where an iBGP peer cannot advertise a route learned from another iBGP peer to another iBGP peer .. Say that 3 times!

This lab also covers BGP filtering by using Prefix-Lists and aggregating addresses AKA BGP Summarization.

GNS3 Lab & Exercise: Configuring IBGP and EBGP Sessions, Local Preference and MED

Fri, 05/28/2010 - 04:32

Keeping it going with BGP here! This is basically lab 3 from the lab portfolio. This one adds some EIGRP into the mix to help demonstrate how to get IGP routes into the routing tables and how that affects the overall routing including BGP.

This lab includes working with IBGP EBGP, the local preference and the Multi-Exit Discriminator

Lab Objectives: In this lab, you will configure both IBGP and EBGP. For IBGP peers in this lab to correctly exchange routing information, the next-hop-self command must be used along with the Local-Preference and MED attributes. This is to insure that
the flat-rate, unlimited-use T1 link is used for sending and receiving data to and from the AS 200 on ISP. The metered T1 should only be used in the event that the primary T1 link has failed. Traffic sent across the metered T1 link offers the same bandwidth of the primary link but at a huge expense. Ensure that this link is not used unnecessarily.

GNS3 Lab & Exercise: BGP Lab - Configuring BGP with Default Routing

Tue, 05/25/2010 - 13:50

Greetings! Hope everyone is wrapping up their CCNP certifications before the July 31st deadlines. If you are still confused about what certs are valid after the deadline and want to know which you should be taking, have a look over here at my attempt to explaining it all.

I’ve been busy trying to absorb all of this study lately and well, It’e been tough! Whats the deal with life? Doesnt it know we want to become certified? So why must it get in the way?

I recently had surgery, the Wife became ill for almost 3 weeks (a very scary situation) and now work is ramping up as will :sigh: it seems almost impossible! Either way, all is well now. I’m back to good health and so is the Wife! Yay!

Ok - this is a simple lab of many that I have that I just need to package and put up. Sorry for the long gaps in between postings - I expect to do a better job once I complete this BSCI exam. I also plan to do a better job at posting lab challenges and scenarios where possible. The biggest problem is I’m still not at a skilled level yet to create any “tough” lab challenges. The best I can do is post what I find and use on my own for studying. I’ve got a lot of labs to post, just be patient with me.

Onto the lab! This is a lab from the Cisco Networking Academy Lab Portforlio.

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

Great source of LOTS and LOTS of labs. The bigger problem is the errors in the material - it can make you crazy. None the less, go through them; try your best and indulge is getting use to the commands more importantly. If you’re at the level where you can detect and mitigate the errors, good for you and please do share. If not - Just focus on the commands. The best way I can recommend coping with the errors, but still making use of it all.
