VLAN间路由

  1. 每个路由器接口对应一个VLAN
    例6-1 配置每个路由器接口对应一个VLAN

    R1# configure terminal
R1(config)# interface f0/0
R1(config-if)# ip address 172.17.10.1 255.255.255.0
R1(config-if)# no shutdown
R1(config-if)# interface f0/1
R1(config-if)# ip address 172.17.30.1 255.255.255.0
R1(config-if)# no shutdown

    例6-2 查看路由表
    R1# show ip route

  2. 单臂路由器
    例6-3 配置子接口

    R1# configure terminal
R1(config)# interface f0/0.10
R1(config-subif)# encapsulation dot1q 10
R1(config-subif)# ip address 172.17.10.1 255.255.255.0
R1(config-subif)# interface f0/0.30
R1(config-subif)# encapsulation dot1q 30
R1(config-subif)# ip address 172.17.30.1 255.255.255.0
R1(config-subif)# interface f0/0
R1(config-if)# no shutdown

  3. 实际配置单臂路由器VLAN间路由
    例6-9 配置单臂路由器：交换机

    S1# configure terminal
S1(config)# vlan 10
S1(config-vlan)# vlan 30
S1(config-vlan)# interface f0/5
S1(config-if)# switchport mode trunk
S1(config-if)# end
S1# copy running-config startup-config

    例6-10 配置单臂路由器

    R1# configure terminal
R1(config)# interface f0/0.10
R1(config-subif)# encapsulation dot1q 10
R1(config-subif)# ip address 172.17.10.1 255.255.255.0
R1(config-subif)# interface f0/0.30
R1(config-subif)# encapsulation dot1q 30
R1(config-subif)# ip address 172.17.30.1 255.255.255.0
R1(config-subif)# interface f0/0
R1(config-if)# no shutdown
