Packet per second performance is constrained a bit, but allowing the actual passage of packets allows things like ping commands, traceroute commands, routing protocols, CDP, and the like to work just like they would on real hardware.ĭynamips does also support the creation of emulated PCs and LAN switches these however do not run a full PC OS or Cisco switch IOS.

If two images were configured to be connected via a point-to-point serial link, Frame Relay PVC, or Ethernet, Dynamips would receive the IOS call to forward the packet, and then deliver that packet to the router on the other end of the link. Dynamips intercepts calls to the router hardware.

You can connect to the Command Line Interface (CLI) of an emulated router, or telnet/ssh to the emulated router, and do all the commands supported by that IOS image.ĭynamips supports multiple emulated routers, the use of emulated serial and Ethernet links, and even the ability to communicate outside the computer running Dynamips through the computer's physical Ethernet interface.

The IOS software has no awareness that it is executing on an emulator. Then, the user (you and me) supplies a copy of the real IOS software that would normally run on real Cisco router hardware of that same model. The Dynamips software acts like Cisco router hardware (several supported models and interface cards). I've also got some handy links listed at the bottom of the page.įirst off, Dynamips emulates Cisco routers and Cisco PIX firewalls. I plan on several more posts about Dynamips and Cisco cert prep this one's just to get use started. I've got a lot of ideas about issues to discuss, but before doing so, today's post will be a kind of level-set on functions, aimed towards those getting ready to embark on their Cisco cert prep.

Many of you have used Dynamips more than I have, and I welcome your comments to clarify, set me straight, and help others learn how to best use it.

So now it's time to do a more substantive discussion, starting with today's post, which is a kind of Dynamips 101 with a cert prep twist.

And occasionally, someone always posts and says the equivalent of 'you can do this for free with Dynamips'. I've also typically ignored the other options, specifically Emulators (aka Dynamips) and Simulators (several). I've spent at least 25% of the space in this blog over the years to a discussion of what used lab gear you might want to get so that you can practice the commands you will see on various Cisco exams. GNS3 software is very excellent complementary tool to real work practice for Network engineer, administrator and other people who want practice and work on real cisco router and switch. Download GNS3 All in one and IOS of router and Switch. Ios xrv and gns3, add cisco ios gns3, cisco ios for dynamips dynagen and gns3. You can download and use Cisco IOS images for GNS3 for free. You may need Cisco IOS images for the GNS3 network simulator program. And relatively challenging for those without the ability to download IOS images.
