Benefits of Using
GNS3 workbench:
GNS3 is
software use for simulating different virtual devices and real devices like
routers, switches etc. It uses Dynamips which is an emulation software to
simulate virtual devices.
It has
several advantage as compare to Packet Tracer (anther network simulator), some
of main features of GNS3 are as under:
- Gns3
uses real IOS software to simulate the different virtual devices, so you enjoy
the new features of IOS with using new IOS in GNS3. Whereas the Packet Tracer is software base simulator
which only allows the limited commands which are programed. Some of new commands may not works
with Packet Tracer.
- One of key advantage of GNS3 is that you can connect the simulated device or network to real world/devices. You can review some of example here. GNS3 Cloud, GNS3 Virtualbox.
- You
can take packet capture with Wireshark between devices which you are
simulating in GNS3.
- GNS3
supports devices and IOS of more vendors like Cisco, Juniper, Linux host etc. as compare to
Packet Tracer.
- The
main advantage
of GNS3 lies in hardware emulation,
since you can connect GNS3 devices to real world therefore you can
ping/telnet GNS3 router from anywhere even from over the internet. Even
you can configure/control the small office network with GNS3 router without using a real router.
- You
can connect and simulate VirtualBox to GNS3 and
can create some of complex network labs.
- You can create your network diagram and can represent
your network architecture easily.
- New versions of GNS3 supports IOU devices as well.
- You can customize virtual devices by adding different
slots and Cards like real network devices.
