Cisco 单臂路由配置实验
拓扑：
交换机配置如下： SW#vlan database SW(vlan)#vlan 2 VLAN 2 added: Name: VLAN0002 SW(vlan)#vlan 3 VLAN 3 added: Name: VLAN0003 SW(vlan)#exit SW(config)#int f0/2 SW(config-if)#switchport mode access SW(config-if)#switchport access vlan 2 SW(config-if)#no shutdown SW(config-if)#int f0/3 SW(config-if)#switchport mode access SW(config-if)#switchport access vlan 3
SW(config-if)#no shutdown SW(config-if)#int f0/1 SW(config-if)#switchport mode trunk SW(config-if)#no shutdown 路由器配置如下： R(config)#int f0/0 R(config-if)#no shutdown R(config-if)#int f0/0.2 R(config-subif)#encapsulation dot1q 2 R(config-subif)#ip address 192.168.2.254 255.255.255.0 R(config-subif)#no shutdown R(config-subif)#int f0/0.3 R(config-subif)#encapsulation dot1q 3 R(config-subif)#ip address 192.168.3.254 255.255.255.0 R(config-subif)#no shutdown R(config-subif)#end 客户机配置如下： HostA: ip:192.168.2.1/24 ip default-gateway:192.168.2.254 HostB: ip:192.168.3.1/24 ip default-gateway:192.168.3.254 测试连通性： HostB#ping 192.168.2.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.2.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 64/95/132 ms
