BUILD VIRTUAL NETWORK LABS USING
CISCO, JUNIPER, AND MORE
GNS3 is open source software that emulates Cisco
router and switch hardware to simulate complex
networks. You can use GNS3 on any computer to
experiment with various router configurations, study
for that next big Cisco certification, or build the
ubernetwork of your wildest dreams—all without
plugging in a single physical network cable.
The Book of GNS3 will teach you how to harness the
powerful GNS3 software to create your own virtual
networks with Cisco and Juniper devices. Hands-on
tutorials throughout show you how to:
• Configure Cisco IOS and ASA devices in GNS3
• Add Juniper routers to your projects with VirtualBox
and QEMU
• Connect GNS3’s hub, switch, and cloud devices to
physical hardware
• Integrate Cisco IOU virtual machines for advanced
switching features
• Simulate a Cisco access server to practice managing
devices
• Build bigger labs by distributing project resources
across multiple computers
Why set up all of that expensive physical hardware
before you know whether it will all work together?
Learn how to build virtual networks with The Book of
GNS3, and stop reconfiguring your lab every time
you want to test something new.
