We all know Dynampis the great Cisco IOS emulator, and VMWare the great OS Virtual Machine.
we can operate both in order to get a fully equiped network infrastructure. But, that will be very heavy on the host PC resources (CPU and RAM).
to connect Virtual PC to Dynamips, we need at first to define Dynamips device to be connected to our physical interface. then connect our virtual PC (vmware) to that physical interface too using either NAT or Bridged connection.
