                          ROUTER ON A STICK INTER-VLAN ROUTING IN GNS3

                How to configure router on stick inter-vlan routing in gns3 with the help of vmware                           machines.

In this scenario XP1,XP2,XP3,XP4 are the 4 virtual machines. This 4 machines  connected to gns3 with 

virtual network in the Vmware.All the virtual network should be in host only mode.
