Core and 2 distribution blocks with L3 and L2 access switches
Written by pierky from http://pierky.tel/ on March 7th, 2009 | 23 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 routers send [...]
GNS3 Topology: MPLS VPN and Traffic Engineering
Written by pierky from http://pierky.tel/ on January 23rd, 2009 | 27 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 Loopback 0 [...]

Written by LBSources from http://www.gns3-labs.com on December 1st, 2008 | 4 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. [...]
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 | 10 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
Feature of Topology: [...]
BSCI OSPF Excercise Sim Question From Jim Shank
Written by LBSources from http://www.gns3-labs.com on November 15th, 2008 | 3 CommentsA fellow reader by the name of Jim has submitted a great SIM lab for all of us BSCI seekers. In the lab he provides a scenario and within the archive he provides a solution file with all the steps to correctly solve the lab. Jim put some great effort into putting the lab together [...]

Topology: MPLS VPNs with MPLS-TE Instead of LDP - OSPF Routing Protocols
Written by LBSources from http://www.gns3-labs.com on July 10th, 2008 | 12 CommentsBased on his 2.0 lab, this is v2.5 by the famous Justine White over at Hacki.AT. I will also put toghether the 3.0 lab also. This is a very high CPU intense lab so be warned. I used 3640 routers to minimize the resource taxing.
As per the Justin in the original thread > MPLS VPNs [...]
