随着Internet的高速发展,网络规模不断膨胀,对于从事网络专业的学生熟练掌握路由器和交换机的配置已显得十分重要。接下来是小编为大家收集的cisco路由器三层交换机简单环境配置实例方法，希望能帮到大家。
cisco路由器三层交换机简单环境配置实例：
一、网络拓扑图：
二、配置命令：
1、路由器的配置：
interface FastEthernet0/0
ip address 10.66.88.222 255.255.255.0
ip nat outside
duplex auto
speed auto
interface FastEthernet0/1
ip address 192.168.1.1 255.255.255.0
ip nat inside
duplex auto
speed auto
interface Vlan1
no ip address
shutdown
ip nat inside source list 1 interface FastEthernet0/0 overload
ip classless
ip route 192.168.2.0 255.255.255.0 192.168.1.222
ip route 192.168.3.0 255.255.255.0 192.168.1.222
access-list 1 permit 192.168.0.0 0.0.255.255
三、三层交换机的配置：
hostname L3-SW
ip dhcp pool vlan2pool
network 192.168.3.0 255.255.255.0
default-router 192.168.3.1
dns-server 202.101.172.35
ip dhcp pool vlan1pool
network 192.168.2.0 255.255.255.0
default-router 192.168.2.1
dns-server 202.101.172.35
interface FastEthernet0/1
no switchport
ip address 192.168.1.222 255.255.255.0
duplex auto
speed auto
interface FastEthernet0/2
switchport mode trunk
interface FastEthernet0/5
switchport mode trunk
interface Vlan1
ip address 192.168.2.1 255.255.255.0
interface Vlan2
ip address 192.168.3.1 255.255.255.0
ip classless
ip route 0.0.0.0 0.0.0.0 192.168.1.1
四、二层交换机的配置：
1、switch0的配置：
hostname sw0
interface FastEthernet0/1
switchport mode trunk
interface FastEthernet0/2
switchport mode access
2、switch1的配置：
hostname sw1
interface FastEthernet0/1
switchport mode trunk
interface FastEthernet0/2
switchport access vlan 2
switchport mode access
