Beginning-Saving and Exporting GNS3 Labs Including Router Configs & Screenshots

REPOST

We have all experienced a time when working in GNS3 and we _think_ we saved the the topology and router configurations. So you open GNS3 and load that config, start them routers, watch them boot all the way to the painful prompt
Would you like to enter the initial configuration dialog? [yes/no]:
And your hard work is [...]

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 Announcement: GNS3 v0.6 Officially Released!

The long anticipated GNS3 v0.6 has been officially released. This version is not so different then the unofficial 0.6 I released some time ago. Minor differences are the bug corrected from them to today. Unfortunately they did not make it to the virtual pc simulation - but Jeremy speculates something about being able to do [...]

WordpressMobile Plugin - Visit GNS3-Labs From Your Mobile Device

While there may not be much benefit from actually making use of the site from your mobile device, its still nice to be able to look at it in an acceptable format to see new posts, comments, etc.
I was looking around for some sort of plugin because I’m always trying to respond to comments and [...]

GNS3-Topology: CCNA & CCNP Full Mesh Topology Template

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 [...]

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. [...]

VLAN Database Lost When Restarting? - Saving VLAN.dat To NVRam

Came across a post online that I thought would help those who have been through the problem and upset of losing VLAN configurations once a router in GNS3 or Dynamips is reloaded. This post explains how to prevent this from happening.
ok, when you restart your Router or you turn off the GNS3, the VLAN configuration [...]

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 Announcement: Want To Run An ASA? At Least Run The Code On PEMU

From the GNS3.net official site..
A new tool called “Cisco image unpacker” has been added on the download page. This tool which is simple to use, can unpack Cisco ASA and IOS images to be used with GNS3, Pemu or Qemu. Please note that at the moment only ASA v7 and early images are supported in [...]

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 [...]
