This chapter show takes you step-by-step through some of the possibilities.
The following topics will be covered in this chapter:

Adding Juniper routers (Junos)
The VirtualBox emulator:
Adding VirtualBox support
A Linux PC on VirtualBox
A Windows PC on VirtualBox
Vyatta router on VirtualBox
By the end of this chapter, you will have a variety of simulation options, ready to tackle some extremely diverse simulations.
