配置如下： 三层交换机上的配置
ip routing
interface FastEthernet0/1
no switchport
ip address 172.16.1.1 255.255.255.252
interface FastEthernet0/3
switchport mode trunk
interface FastEthernet0/4
switchport mode trunk
interface Vlan2
ip address 192.168.2.1 255.255.255.0
interface Vlan3
ip address 192.168.3.1 255.255.255.0
interface Vlan4
ip address 192.168.4.254 255.255.255.0
interface Vlan5
ip address 192.168.5.254 255.255.255.0
ip classless
ip route 0.0.0.0 0.0.0.0 172.16.1.2
路由器上的配置是
interface FastEthernet0/0
ip address 10.1.1.1 255.255.255.0
no shut
interface FastEthernet0/1
ip address 172.16.1.2 255.255.255.252
no shut
ip route 0.0.0.0 0.0.0.0 172.16.1.1
左边两层交换机配置
interface FastEthernet0/1
switchport access vlan 2
no shut
interface FastEthernet0/2
switchport access vlan 3
no shut
interface FastEthernet0/3
switchport mode trunk
右边交换机的配置
interface FastEthernet0/1
switchport access vlan 4
no shut
interface FastEthernet0/2
switchport access vlan 5
no shut
interface FastEthernet0/4
switchport mode trunk 配置完成 实现内网与外网的互通。
