It is simply a complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA/CCNP. Of course, this emulator cannot replace a real router. It uses real Cisco IOS Images, which are not included in this package. The emulator engine will work in a virtual host savagely consuming virtual CPU and memory resources, yet, the forged MAC addresses may not exit your hypervisor virtual switch. Emulates Cisco routers on a traditional PC. What will not work: Virtualizing dynamips itself is tricky. What will work: All popular Cisco IOS devices with most linecards, JunOS Olive.

Using a sniffer you can actually see real packets (with Cisco MAC prefixes and stuff) from your virtual devices swimming in your LAN.

Communication with the real world (the wire) is done via tap and bridge interfaces. CPU and mem usage go skyhigh, but then, you have your own virtual private lab. You design the topology via a snappy GUI (that is, GNS3), configure your virtual gear and then GNS3 fires up the emulators underneath. Hot Standby Router Protocol (HSRP) is a Cisco proprietary First Hop. JunOS on the other hand is emulated with qemu using Olive, a stripped down version of JunOS, sort of an SDK. The GNS3 server manages emulators such as Dynamips, VirtualBox or Qemu/KVM. How it works in a few words: MIPS and PPC based hardware (Cisco 26xx, 36XX, 37xx, 72xx) is emulated via dynamips running the IOS image unchanges.

My recommendation for the OS is Ubuntu with readily donwloadable and installable packages of all bits and pieces (# apt-get install gns3), however windows works just fine but with the 4GB constrains for a 32bit OS. The first is easy to do, for the second you will need access to licensed software or the actual hardware itself. What you will need is a decent PC with lots of memory (4GB to start with plus a fast CPU) and IOS/JunOS software images.
