Cisco network device administrator or want can be done by the relevant experiments to simulate the actions stakeholders CCNA, CCNP, CCIE and other Cisco certification exam through it. It also can be used for virtual experience Cisco IOS IOS or test to be deployed configuration implemented on a real router.
Simply put it is a graphical front-end dynamips directly compared to the use of such dynamips virtualization software easier to use and to be more operational.

6. Select the path you want to install, remember not to have Chinese, and then click Install to install.
7. then will automatically start the virtual machine, click Next.
8. The consent agreement, then the next step.
9. boot, there is a need on the hook, and then click Install.

8. The configuration of the two vpc ipd address, to ensure that the same gateway.
9.ping at each other ip see if I can pass.
Vmware use in connecting two switch interconnection GNS3
1. First, create two virtual machines in VMware.
2. Configure the card two virtual machines.

5. Create a router and two Host, and add a second floor to the router boards, as above.
6. Host connected by lines and the router interface.
7. Then turn on the router.
8. ping each virtual machine, can not see through.
