cisco 命令 路由 是实现 不同的 vlan 通信

R1:
interface FastEthernet0/0
no ip address
duplex full
!
interface FastEthernet0/0.10
encapsulation dot1Q 10
ip address 192.168.10.1 255.255.255.0
!
interface FastEthernet0/0.11
encapsulation dot1Q 11
ip address 192.168.11.1 255.255.255.0

R3:
!
interface FastEthernet0/0
ip address 192.168.10.2 255.255.255.0
