R1、R2為交換機，R3～R5為pc，R6為路由器 R3(config)#no ip routing R3(config)#int f0/0 R3(config-if)#ip add 192.168.10.1 255.255.255.0 R3(config-if)#no shut R3(config-if)#end R3(config)#ip default-gateway 192.168.10.254 R3#show ip route Default gateway is 192.168.10.254 Host Gateway Last Use Total Uses Interface ICMP redirect cache is empty R4(config)#no ip routing R4(config)#int f0/0 R4(config-if)#ip add 192.168.20.1 255.255.255.0 R4(config-if)#no shut R4(config-if)#end R4(config)#ip default-gateway 192.168.20.254 R4#show ip route Default gateway is 192.168.20.254 Host Gateway Last Use Total Uses Interface ICMP redirect cache is empty R5(config)#no ip routing R5(config)#int f0/0 R5(config-if)#ip add 192.168.10.2 255.255.255.0 R5(config-if)#no shut R5(config-if)#end R5(config)#ip default-gateway 192.168.10.254 R5#show ip route Default gateway is 192.168.10.254 Host Gateway Last Use Total Uses Interface ICMP redirect cache is empty R1#vlan database R1(vlan)#vlan 10 VLAN 10 added: Name: VLAN0010 R1(vlan)#vlan 20 VLAN 20 added: Name: VLAN0020 R1(vlan)#exit R1#conf t R1(config)#int f0/0 R1(config-if)#switchport mode access R1(config-if)#switchport access vlan 10 R1(config-if)#int f0/1 R1(config-if)#switchport mode access R1(config-if)#switchport access vlan 20 R1(config-if)#end R1(config)#int f0/15 R1(config-if)#switchport trunk encapsulation dot1q R1(config-if)#switchport mode trunk R1(config-if)#end R2#vlan database R2(vlan)#vlan 10 VLAN 10 added: Name: VLAN0010 R2(vlan)#vlan 20 VLAN 20 added: Name: VLAN0020 R2(vlan)#exit R2#conf t R2(config)#int f0/0 R2(config-if)#switchport mode access R2(config-if)#switchport access vlan 10 R2(config-if)#int f0/1 R2(config-if)#switchport trunk encapsulation dot1q R2(config-if)#switchport mode trunk R2(config-if)#end R2(config)#int f0/15 R2(config-if)#switchport trunk encapsulation dot1q R2(config-if)#switchport mode trunk R2(config-if)#end R6(config)#int f0/0 R6(config-if)#no shut 先開啟物理介面 R6(config-if)#end R6(config)#int f0/0.10 R6(config-subif)#encapsulation dot1Q 10 R6(config-subif)#ip add 192.168.10.254 255.255.255.0 R6(config-subif)#no shut R6(config-subif)#exit R6(config)#int f0/0.20 R6(config-subif)#encapsulation dot1Q 20 R6(config-subif)#ip address 192.168.20.254 255.255.255.0 R6(config-subif)#no shut 到此實現了不同vlan和不同網段之間的互通！ default interface f0/0 此命令將介面設為預設值
