单臂路由实验

 一：实验拓扑

 

二、IP地址规划

PC1: 192.168.10.11/24    网关192.168.10.254/24    F 0/1    VLAN10

PC2: 192.168.20.22/24    网关192.168.20.254/24    F 0/2    VLAN20

PC3: 192.168.30.33/24    网关192.168.30.254/24    F0/3     VLAN30

1841:  F 0/0.1    192.168.10.254       VLAN10

           F 0/0.2    192.168.20.254       VLAN20

           F 0/0.3    192.168.30.254        VLAN30   

三、实验需求

实现不同VLAN之间的通信。

四、配置思路

交换机端口分别为不同VLAN，连接路由器端口起Trunk。路由器连接交换机的端口配置子接口。

五、配置脚本：

sw
!
enable
config terminal
vlan 10
vlan 20
vlan 30
exit
interface fastethernet 0/1
switchport mode access
switchport access vlan 10
exit

interface fastethernet 0/2
switchport mode access
switchport access vlan 20
exit

interface fastethernet 0/3
switchport mode access
switchport access vlan 30
exit
interface fastethernet 0/5
switchport mode trunk
switchport trunk native vlan 6

switchport trunk allowed vlan 10,20,30
end
!

!
enable
config terminal
no ip domain-lookup
interface fastethernet 0/0
no shutdown
exit
interface fastethernet 0/0.1
encapsulation dot1q 10
ip address 192.168.10.254 255.255.255.0
exit
interface fastethernet 0/0.2
encapsulation dot1q 20
ip address 192.168.20.254 255.255.255.0
exit
interface fastethernet 0/0.3
encapsulation dot1q 30
ip address 192.168.30.254 255.255.255.0
end
