GNS3-Topology: EvilRouters-Weighting To Influence BGP Routing

Written by LBSources from http://www.gns3-labs.com on March 14th, 2009 | 6 Comments

This is an older lab that is part of the BGP series labs that Jeremy over at EvilRouters.net is building. The labs are great and they will surely serve someone some great lab experience by the time hes done with them all. This lab picks up from: EvilRouters.net – Configuring Basic BGP GNS3-Topology: EvilRouters- BGP [...]

Core and 2 distribution blocks with L3 and L2 access switches

Written by pierky from http://pierky.tel/ on March 7th, 2009 | 33 Comments

I 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 | 61 Comments

Another 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 | 17 Comments

BGP 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 [...]

My 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 | 19 Comments

Chris 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 [...]

We have another great helper to the site. Mike Litka has shared a topology he put together while at Cisco Networkers 2008. He also put these labs together using the DynaSlaxGNS3 livecd. He has always had issues with GNS3 crashing on his pc, but since using the livecd he’s had no problems at all. Give [...]
