实验02 VLAN与单臂路由

一、拓扑图

二、实验目标

1．实现小型企业局域网二层广播域VLAN隔离和三层全网全连通。

2．掌握VLAN、Trunk、单臂路由的配置方法。

3．分析PC1 ping PC4 的三层通信过程和二层通信过程。

4．分析PC4 ping SW4网管地址的三层通信过程和二层通信过程。

三、实验内容

（1）SW3，SW4，RT5的基本信息配置

Switch(config-line)# logging synchronous

Switch(config-line)# exec-timeout 0 0

Switch(config-line)# no login

Switch(config-line)#line aux 0

Switch(config-line)# logging synchronous

Switch(config-line)# exec-timeout 0 0

Switch(config-line)# no login

Switch(config-line)# privilege level 15

Switch(config-line)#line vty 0 4

Switch(config-line)# no login

Switch(config-line)# privilege level 15

Switch(config-line)#exit

Switch(config)#no cdp run

Switch(config)#no ip http server

（2）创建Vlan

SW4#vlan database

SW4(vlan)#vlan 8

VLAN 8 added:

Name: VLAN0008

SW4(vlan)#vlan 10

VLAN 10 added:

Name: VLAN0010

SW4(vlan)#vlan 11

VLAN 11 added:

Name: VLAN0011

SW4(vlan)#exi

APPLY completed.

Exiting....

SW3#vlan database

SW3(vlan)#vlan 8

VLAN 8 added:

Name: VLAN0008

SW3(vlan)#vlan 10

VLAN 10 added:

Name: VLAN0010

SW3(vlan)#vlan 11

VLAN 11 added:

Name: VLAN0011

SW3(vlan)#exi

APPLY completed.

Exiting....

（3）SW3的二层接口配置

SW3(config)#interface fastEthernet 0/10

SW3(config-if)#switchport mode access

SW3(config-if)#switchport access vlan 10

SW3(config-if)#exit

SW3(config)#interface fastEthernet 0/11

SW3(config-if)#switchport mode access

SW3(config-if)#switchport access vlan 11

SW3(config-if)#exit

SW3(config)#interface fastEthernet 0/1

SW3(config-if)#switchport trunk encapsulation dot1q

SW3(config-if)#switchport mode trunk

*Mar 1 00:03:59.883: %DTP-5-TRUNKPORTON: Port Fa0/1 has become dot1q trunk

SW3(config-if)#switchport trunk allowed vlan all

SW3(config-if)#switchport trunk native vlan 8

SW3(config-if)#exit

SW3(config)#interface fastEthernet 0/3

SW3(config-if)#switchport trunk encapsulation dot1q

SW3(config-if)#switchport mode trunk

*Mar 1 00:04:43.355: %DTP-5-TRUNKPORTON: Port Fa0/3 has become dot1q trunk

SW3(config-if)#switchport trunk allowed vlan all

SW3(config-if)#exit

SW4的二层接口配置

SW4(config)#interface fastEthernet 0/10

SW4(config-if)#switchport mode access

SW4(config-if)#switchport access vlan 10

SW4(config-if)#exit

SW4(config)#interface fastEthernet 0/11

SW4(config-if)#switchport mode access

SW4(config-if)#switchport access vlan 11

SW4(config-if)#exit

SW4(config)#interface fastEthernet 0/3

SW4(config-if)#switchport trunk encapsulation dot1q

SW4(config-if)#switchport mode trunk

*Mar 1 00:12:18.667: %DTP-5-TRUNKPORTON: Port Fa0/3 has become dot1q trunk

SW4(config-if)#switchport trunk allowed vlan all

SW4(config-if)#exit

(4)SW3网管IP

SW3(config)#interface vlan 8

*Mar 1 00:04:56.091: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan8, changed state to up

SW3(config-if)#ip address 192.168.8.130 255.255.255.128

SW3(config-if)#no shutdown

SW3(config-if)#exit

SW3(config)#ip default-gateway 192.168.8.129

SW4网管IP

SW4(config)#interface vlan 8

*Mar 1 00:12:29.119: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan8, changed state to up

SW4(config-if)#ip add 192.168.8.131 255.255.255.128

SW4(config-if)#no shutdown

SW4(config-if)#exit

SW4(config)#ip default-gateway 192.168.8.129

(5)RT5的三层接口配置

RT5(config)#interface ethernet 0/0

RT5(config-if)#ip ad

RT5(config-if)#ip address 192.168.8.129 255.255.255.128

RT5(config-if)#no shutdown

*Mar 1 00:31:00.243: %LINK-3-UPDOWN: Interface Ethernet0/0, changed state to up

*Mar 1 00:31:01.243: %LINEPROTO-5-UPDOWN: Line protocol on Interface Ethernet0/0, changed state to up

RT5(config-if)#exit

RT5(config-subif)#interface ethernet 0/0.10
