GNS3 Lab & Excercise: OSPF Hub-And-Spoke & Virtual Links

Ok - So here is another CCNP BSCI / CCNA lab challenge. This lab is part of Chris Bryant’s CCNP lab manual. I haven’t included the solutions yet - I’ll give it some time and post that later .. First work on completing the lab and getting it to all work per the challenge.
Ok [...]

GNS3-Topology: ACL Test Lab for ACLs and NAT/PAT

“Hello World!’ - Hey so it’s been while since posting last and some things are getting back to normal since the move. One of them is my office Very happy about that! One thing that has not gotten back to normal is routine studying - I’m so far behind from my goal - but [...]

GNS3-Topology: Dual WAN connection on Cisco with Policy-based routing (PBR)

Pierky put together a great exercise lab giving you a scenario and objective. The solution is in a DOC file in the archive package.
Scenario
We have a router connected to the ISP with two WAN connections:
- a Bronze link, with little bandwidth, on which we have a /30 subnet;
- a Gold link, with good performances, on [...]

GNS3-Topology: EvilRouters-Weighting To Influence BGP Routing

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 Over Multilink PPP [...]

Core and 2 distribution blocks with L3 and L2 access switches

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 routers send [...]

GNS3 Topology: MPLS VPN and Traffic Engineering

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 Loopback 0 [...]

GNS3-Topology: EvilRouters- BGP Over Multilink PPP Lab

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 [...]

GNS3-Topology: EvilRouters - Multilink-PPP Lab

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 a [...]

GNS3 Topology: BSCI - EIGRP & ISIS Redistribution Lab

On 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: EvilRouters.Net - Basic IPSec VPN Over Frame-Relay Lab

Jeremy (AKA Jlgaddis) over at EvilRouters.net created 2 cool labs. 1 was a basic frame-relay lab and the other was adding IPSec VPN to the lab. He gave some great details and outlined the configuration - step by step. I compiled the lab for GNS3 specifically.
Jeremy has an awesome blog .. check him out @ [...]

GNS3 Topology: Multicasting - PIM Sparse-Mode - Anycast RP and MSDP - IPmc Lab

Here is a very new lab to GNS3-Labs which we havent had before. We have plenty of OSPF, RIP and all the other common routing protocols and what not. Pierky has created this very cool lab featuring Multicast, PIM Sparse-mode, Anycast RP, MSDP. Hope you enjoy!
A source (Sender) needs to send a multicast ping to [...]

GNS3 Topology: Featuring - Virtual Area Links, Multi and Inter Area OSPF & Some Redistribution

Found 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: [...]

Topology: Multilayer Switching in a “Campus” Network

Hey we have yet another great lab from a contributor. His name is Pierky and this is one great lab ..
You can also post your labs by sending them to me or by creating an account or making the post yourself and I will approve it once its complete ..
I’m working on CCNP BCMSN exam [...]

Topology: Cisco Networkers 2008 - LABCRT-2106-OSPF-Start

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 the [...]

GNS3 Tutorials: BlindHog - How to build a switching lab

In case you have had a look at our Topology: VLAN Trunking GNS3 Lab - 802.1Q - Router On A Stick & need some help with configurations have a look over at BlindHog.
As per BlindHog:
In this tutorial, you will learn how to build a Cisco switching lab … even though GNS3 cannot emulate a Cisco [...]
