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: Small Site Multihoming

Hey 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 how [...]

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 [...]

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 [...]

BSCI OSPF Excercise Sim Question From Jim Shank

A 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: Configuring BGP with Default Routing Lab 6-1

Hey folks it seems we have a helper who is willing to share labs with us all! His name is Amir Hussain and he will be sharing his labs based on the BSCI v50 Lab Guide by Cisco.
You too can share your labs and co-admin this site by shooting me an email at postmy [AT] gns3-labs [...]
