思科單臂路由配置
網絡的組建:
路由器F0/0端口與交換機的上聯端口F0/5相連,交換機的下聯端口F0/11和F0/12分別接PC1和PC2,交換機下聯口劃分爲兩個VLAN,分別是
路由器F0/0端口與交換機的上聯端口F0/5相連,交換機的下聯端口F0/11和F0/12分別接PC1和PC2,交換機下聯口劃分爲兩個VLAN,分別是
VLAN10和VLAN20,其中PC1屬於VLAN10,PC2屬於VLAN20;
1、路由器的配置:
R1(config)#int f0/0 //進入f0/0端口;
R1(config-if)#no sh //打開端口;
R1(config-if)#int f0/0.1 //進入f0/0子端口1;
R1(config-subif)#ip add 192.168.1.1 255.255.255.0 //配置IP地址;
R1(config-subif)#encapsulation dot1q 10 //用IEEE802.Q封裝協議封裝,指定給VLAN 10
R1(config-subif)#no sh
R1(config-subif)#int f0/0.2 //進入f0/0子端口2;
R1(config-subif)#ip add 192.168.2.1 255.255.255.0 //配置IP地址;
R1(config-subif)#encapsulation dot1q 20 //用IEEE802.Q封裝協議封裝,指定給VLAN 20
R1(config-subif)#no sh
R1(config)#int f0/0 //進入f0/0端口;
R1(config-if)#no sh //打開端口;
R1(config-if)#int f0/0.1 //進入f0/0子端口1;
R1(config-subif)#ip add 192.168.1.1 255.255.255.0 //配置IP地址;
R1(config-subif)#encapsulation dot1q 10 //用IEEE802.Q封裝協議封裝,指定給VLAN 10
R1(config-subif)#no sh
R1(config-subif)#int f0/0.2 //進入f0/0子端口2;
R1(config-subif)#ip add 192.168.2.1 255.255.255.0 //配置IP地址;
R1(config-subif)#encapsulation dot1q 20 //用IEEE802.Q封裝協議封裝,指定給VLAN 20
R1(config-subif)#no sh

2.交換機上的配置:
SW1(config)#int f1/5 //進入f1/5端口;
SW1(config-if)#switchport mode trunk //設置幹道模式;
SW1(config-if)#switchport trunk encapsulation dot1q //用IEEE802.Q封裝協議封裝;
SW1(config-if)#no sh
SW1(config-if)#end
SW1#vlan database //進入vlan配置模式;
SW1(vlan)#vlan 10 name v10 //新建VLAN 10;
SW1(vlan)#vlan 20 name v20 //新建VLAN 20;
SW1#conf t
SW1(config)#int f1/11
SW1(config-if)#switchport access vlan 10 //把f1/11端口劃分給VLAN 10;
SW1(config-if)#no sh
SW1(config-if)#int f1/12
SW1(config-if)#switchport access vlan 20 //把f1/11端口劃分給VLAN 10;
SW1(config-if)#no sh
2.交換機上的配置:

SW1(config-if)#switchport trunk encapsulation dot1q //用IEEE802.Q封裝協議封裝;
SW1(config-if)#no sh
SW1(config-if)#end
SW1#vlan database //進入vlan配置模式;
SW1(vlan)#vlan 10 name v10 //新建VLAN 10;
SW1(vlan)#vlan 20 name v20 //新建VLAN 20;
SW1#conf t
SW1(config)#int f1/11
SW1(config-if)#switchport access vlan 10 //把f1/11端口劃分給VLAN 10;
SW1(config-if)#no sh
SW1(config-if)#int f1/12
SW1(config-if)#switchport access vlan 20 //把f1/11端口劃分給VLAN 10;
SW1(config-if)#no sh

PC1上的配置:
PC1#if eth0 192.168.1.100 netmask 255.255.255.0 //配置IP地址;
PC1# route add default gw 192.168.1.1 //配置網關;
PC1上的配置:
PC1#if eth0 192.168.1.100 netmask 255.255.255.0 //配置IP地址;
PC1# route add default gw 192.168.1.1 //配置網關;
PC2上的配置:
PC2#if eth0 192.168.2.100 netmask 255.255.255.0 //配置IP地址;
PC2# route add default gw 192.168.2.1 //配置網關;
PC2#if eth0 192.168.2.100 netmask 255.255.255.0 //配置IP地址;
PC2# route add default gw 192.168.2.1 //配置網關;
