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

Written by LBSources from http://www.gns3-labs.com on July 6th, 2010 | 2 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!

GNS3 Lab & Exercise: EIGRP & OSPF Route Manipulation

Written by LBSources from http://www.gns3-labs.com on June 26th, 2010 | 1 Comment

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! :)

Packet Pushers Podcasts - Listen In!!!

Written by LBSources from http://www.gns3-labs.com on June 22nd, 2010 | 2 Comments

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!

Using Microcore Linux in GNS3 To Simulate PC/Workstations/Computers

Written by LBSources from http://www.gns3-labs.com on June 20th, 2010 | 1 Comment

So, you read in the latest release notes of GNS3 0.7.2 the ability to simulate PCs/Hosts/Workstation/Computers, etc and you dont know where to begin? Well, fellow Moderator of the GNS3 forums Kage, put together a very simple, clear and step by step document to getting started.

Using Microcore Linux in GNS3 To Simulate PC/Workstations/Computers

Thanks Kage!

Any assistance you need RE the use of Microcore should be directed to the GNS3 forums, NOT here :) I’m no expert..

If you have a hard time getting Microcore working - you can always try vpcs - Documentation can be found here -> How to simulate PC/Workstations/Hosts/Computers using vpcs

Cheers!

GNS3 Lab & Exercise: OSPF Case Study & Lab Scenario 2

Written by LBSources from http://www.gns3-labs.com on June 19th, 2010 | 0 Comments

How are we doing? I’m continuing on working to complete this lab book and all the labs :)

This is another OSPF related lab from the Cisco Networking Academy Lab Portfolio. No EIGRP or other protocols involved. This lab involves the use of sub-interfaces, which changes your frame-relay statements - watch out and don’t get too confused :)

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 :)

GNS3 Official Release: GNS3 0.7.2

Written by LBSources from http://www.gns3-labs.com on June 16th, 2010 | 6 Comments

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..

GNS3-Lab & Exercise - BGP Route Reflectors & Filters

Written by LBSources from http://www.gns3-labs.com on June 4th, 2010 | 0 Comments

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

Written by LBSources from http://www.gns3-labs.com on May 27th, 2010 | 1 Comment

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
