GNS3 – Graphical Network Simulator

GNS3 is a graphical network simulator that allows simulation of complex networks. It is an excellent complementary tool to real labs for Cisco and Juniper network engineers, administrators and people wanting to pass certifications such as CCNA, CCNP, CCIP, CCIE, JNCIA, JNCIS, JNCIE. This project is an open source, free program that may be used on multiple operating systems, including Windows, Linux, and MacOS X.

Features overview

• You can design of high quality and complex network topologies.
• Emulation of many Cisco IOS router platforms, IPS, PIX and ASA firewalls, JunOS.
• Simulation of simple Ethernet, ATM and Frame Relay switches.
• Connection of the simulated network to the real world!
• Packet capture using Wireshark.

Note: users have to provide their own IOS/IPS/PIX/ASA/JunOS to use with GNS3.

MIMIC CCNA Virtual Lab Simulator

MIMIC Virtual Lab creates a real world lab environment with a network of Cisco Routers and Switches. It gives hands-on learning experience without buying expensive equipment.
MIMIC Virtual Lab CCNA is sold in two versions:
MIMIC Virtual Lab CCNA and
MIMIC Virtual Lab CCNA Plus
MIMIC gives Network Engineers the ability to practice for CCNA and other certifications instead of just reading instructions. It enables Training organizations to supply a Virtual lab to students with the classroom training or e-learning courses. Students can interact with Routers and Switches, just like with real devices.

Getting dynamips is easy…it’s a freeware router simulation program. Installing dynamips is not so easy.
This tutorial helps bridge that gap as well as pointing out additional freeware apps you will need and links to labs.
