思科路由器交换机实现单臂路由的方法

CISCO路由器实现单臂路由的配置方法

连接如上图,ROUTET的F1/0与SWITCH的F0/0相连,SWITCH的F0/1,F0/2,F0/3分别与PC1,PC2,PC3相连接,PC1分到VLAN10, PC2,PC3分到VLAN 20 1.路由器的配置

注意的地方,在子接口先要先描术DOT1Q,再配IP地址,DOT1Q后面的数字是VLAN的号码,根据交换机的配置不同有所不同

Router>enable Router#configure terminal Router(config)#int f1/0 Router(config-if)#no shut Router(config)#int f 1/0.1

Router(config-subif)#encapsulation dot1q 10//描术子接口的类型为dot1q Router(config-subif)#ip add 192.168.1.254 255.255.255.0 Router(config-subif)#exit Router(config)#int f1/0.2

Router(config-subif)#encapsulation dot1q 20//描术子接口的类型为dot1q Router(config-subif)#ip add 192.168.2.254 255.255.255.0 Router(config-subif)#exit Router#copy run star 2交换机的配置 Switch>enable

Switch#vlan database Switch(vlan)#vlan 10 Switch(vlan)#vlan 20 Switch(vlan)#exit

Switch#configure terminal Switch(config)#int f0/0

Switch(config-if)#switchport mode trunk//把接品设成trunk模式, Switch(config)#int f0/1

Switch(config-if)#switchport access vlan 10

Switch(config-if)#exit Switch(config)#int f0/2

Switch(config-if)#switchport access vlan 20 Switch(config-if)#exit Switch(config)#int f0/3

Switch(config-if)#switchport access vlan 20 Switch(config-if)#exit 3.PC机的配置

PC1: IP地址:192.168.1.1 子网掩码:255.255.255.0 默认网关:192.168.1.254 PC2: IP地址:192.168.2.1 子网掩码:255.255.255.0 默认网关:192.168.2.254 PC3: IP地址:192.168.2.2 子网掩码:255.255.255.0 默认网关:192.168.2.254 4配置成功后的测试

需求:在局域网中,通过交换机上配置VLAN可以减少主机通信广播域的范围,当VLAN之间有部分主机需要通信,但交换机不支持三层交换时,可以采用一台支持802.1Q的路由器实现VLAN的互通.这需要在以太口上建立子接口,分配IP地址作为该VLAN的网关,同时启动802.1Q.

组网:路由器E0端口与交换机的上行trunk端口(第24端口)相连,交换机下行口划分3个VLAN,带若干主机.

拓扑图如下：

1.路由器的配置

[Router]

[Router]inter e0

[Router-Ethernet0]ip add 10.0.0.1 255.255.255.0 [Router-Ethernet0]inter e0.1 //定义子接口E0.1

[Router-Ethernet0.1]ip add 172.16.1.1 255.255.255.0

[Router-Ethernet0.1]vlan-type dot1q vid 1 //指定以太网子接口属于VLAN1,此命令应用在以太网子接口

上。只有配置了该命令之后，以太网子接口才会根据配置的VLAN ID 号在以太网帧头中嵌入VLAN 标签，与该网

口相连的交换机接口才能正确处理接收到的帧。 [Router-Ethernet0.1]inter e0.2 //定义子接口E0.2 [Router-Ethernet0.2]ip add 172.16.2.1 255.255.255.0

[Router-Ethernet0.2]vlan-type dot1q vid 2 //指定以太网子接口属于VLAN2 [Router-Ethernet0.2]inter e0.3 //定义子接口E0.3 [Router-Ethernet0.3]ip add 172.16.3.1 255.255.255.0

[Router-Ethernet0.3]vlan-type dot1q vid 3 //指定以太网子接口属于VLAN3 [Router-Ethernet0.3]inter e0 [Router-Ethernet0]undo shut % Interface Ethernet0 is up

[Router-Ethernet0] //用网线将E0端口连到S3026第24端口 :46:32: Interface Ethernet0 changed state to UP

:46:32: Line protocol ip on interface Ethernet0, changed state to UP :46:32: Line protocol ip on interface Ethernet0.1, changed state to UP :46:32: Line protocol ip on interface Ethernet0.2, changed state to UP :46:32: Line protocol ip on interface Ethernet0.3, changed state to UP 2.交换机的配置

[Quidway-vlan1]vlan 2

[Quidway-vlan2]port ethernet 0/17 to eth 0/19 eth 0/22 //将第17至19端口，和第22端口加入VLAN2

[Quidway-vlan2]vlan 3

[Quidway-vlan3]port eth 0/21 //将第21端口加入VLAN2 [Quidway-vlan3]inter e0/24

[Quidway-Ethernet0/24]port link-type trunk //将第24端口设为trunk口

[Quidway-Ethernet0/24]port trunk permit vlan all //允许所有VLAN流量通过 Please wait........................................... Done.

[Quidway-Ethernet0/24]dis port trunk //检验TRUNK口配置 Now, the following trunking ports exist: Ethernet0/24

[Quidway-Ethernet0/24]dis vlan 2 //检验VLAN2的配置 VLAN ID: 2

VLAN Type: static

Route Interface: not configured Description: VLAN 0002 Tagged Ports: Ethernet0/24 Untagged Ports:

Ethernet0/17 Ethernet0/18 Ethernet0/19 Ethernet0/22

[Quidway-Ethernet0/24]dis vlan 3 //检验VLAN3的配置 VLAN ID: 3

VLAN Type: static

Route Interface: not configured Description: VLAN 0003 Tagged Ports: Ethernet0/24 Untagged Ports: Ethernet0/21

3.在工作站上检查网络是否连通。此工作站连接S3026第21端口，属于VLAN2。
