Problem

GNS3 Unable to Create Generic Ethernet NIO Mac OS X

Solution

Gns3和vmware fusion下linux主機互通

1. Sudo 許可權進入gns3，否則不能正常開啟需要的3080埠，做橋接
   sudo /Applications/GNS3.app/Contents/MacOS/gns3
2. 設定cloud為vnet1網口，並設定router的ip地址為vnet1網段無衝突的任意地址

R1#configure terminal
R1(config)#interface fastEthernet 0/0
R1(config-if
 
)#ip address 172.16.232.232 255.255.255.0
R1(config-if)#no sh
R1(config-if)#en
R1(config)#hostname cisco
cisco(config)#crypto key generate rsa general-keys modulus 1024
cisco(config)#ip domain-name cisco
cisco(config)#line vty 0 4
cisco(config-line)#login local
cisco(config-line)#transport input ssh telnet
cisco(config-line
 
)#en
cisco(config)#enable password cisco
cisco(config)#en
cisco#copy running-config startup-config
