GNS3-Topology: NBMA over FRAME RELAY LAB
Written by LBSources from http://www.gns3-labs.com on June 13th, 2009 | 6 CommentsA member of the site name Angel Canario shared a basic lab topology that he put together. It’s not a lab exercise, but like many labs and topologies on the site; they can helpful to someone eventually. Angel has found this site to be very useful and says he’d donate all labs he creates once [...]
GNS3-Topology: Small Site Multihoming
Written by brahadesh from on May 15th, 2009 | 5 CommentsHey we have another contributed lab. This one comes from Brahadesh.. He put together a little lab based on a exercise from another site and contributed it here to us. It’s great that you can find an exercise on the internet, whip it up real quick, work on it and share it afterward. It’s amazing [...]
GNS3-Topology: Dual WAN connection on Cisco with Policy-based routing (PBR)
Written by pierky from http://pierky.tel/ on April 14th, 2009 | 10 CommentsPierky put together a great exercise lab giving you a scenario and objective. The solution is in a DOC file in the archive package.

Core and 2 distribution blocks with L3 and L2 access switches
Written by pierky from http://pierky.tel/ on March 7th, 2009 | 24 CommentsI just arranged this lab I used when I was studying for CCNP, I hope someone will find it useful. We have a 2 distribution blocks network linked with the core layer; all elements are dual linked to the upstream layer for redundancy. Block 1 has L3 access switches, running EIGRP as stub routers. Distribution [...]
GNS3 Topology: MPLS VPN and Traffic Engineering
Written by pierky from http://pierky.tel/ on January 23rd, 2009 | 51 CommentsAnother great lab from Pierky! Thanks!! Routers P1, P2, P3 and P4 are in the core, just running OSPF in area 0. Each router has Loopback 0 with address 10.0.1.x (where x is the router number – P1 = 10.0.1.1). Provider-edge routers PE1, PE2, PE3 and PE4 run OSPF in area 0 too; they have [...]
GNS3-Topology: EvilRouters- BGP Over Multilink PPP Lab
Written by LBSources from http://www.gns3-labs.com on January 11th, 2009 | 4 CommentsBGP for me is one hell of an interesting routing protocol. Until I got into working with enterprise networks, I never realized how much it was used. After working with it now for about 2 years, it’s really grown on me and is a part of the CCNP study which I cant wait to make [...]
GNS3-Topology: EvilRouters – Multilink-PPP Lab
Written by LBSources from http://www.gns3-labs.com on December 21st, 2008 | 1 CommentMy buddy Jeremy over at EvilRouters does a great job at taking you through his labs. He includes great details and steps to getting the configurations and challenge completed. He also speaks in very simple terms which shows he cares about people understanding more than he likes hearing himself talk technical. The lab below is [...]
GNS3-Topology: CCNA & CCNP Full Mesh Topology Template
Written by LBSources from http://www.gns3-labs.com on December 1st, 2008 | 13 CommentsChris sent me a lab which he says has helped him to work on about 95% of his CCNA and CCNP lab requirements. I think this is a clear sign that using Dynamips or GNS3 can be effective in a big way with exam preperation. That 5% left over can be achieved in a few [...]

Written by LBSources from http://www.gns3-labs.com on December 1st, 2008 | 5 CommentsOn November 15th I posted a lab contributed:BSCI OSPF Excercise Sim Question From Jim Shank. The lab was a great excercise where Jim pitched a scenario and requirement and the solution. Great lab! Jim sent me a new lab to share which is even better and has often proven to be a challenge for many. [...]

A source (Sender) needs to send a multicast ping [...]
GNS3 Topology: Featuring – Virtual Area Links, Multi and Inter Area OSPF & Some Redistribution
Written by LBSources from http://www.gns3-labs.com on November 21st, 2008 | 11 CommentsFound a nice OSPF lab over at the GNS3.net forums, but it wasn’t properly exported and packaged. So I did what I always do .. Put it together, cleaned it up and tested and it works flawlessly. Very nice lab with virtual area links, RIP redistribution, inter-area and multi-area OSPF. Routers Used: 3640 IOS: c3640-ik9o3s-mz.124-17a [...]
