單臂路由的配置
實驗拓撲圖：
實驗要求：
在Router上配置單臂路由，實現不同vlan之間的通訊。
實驗過程
1.在switch上劃分兩個vlan，並把f0/2劃分進vlan10，把f0/3劃分進vlan20
|
Router>en Router#config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#no ip domain-lookup Router(config)#line console 0 Router(config-line)#no exec-timeout Router(config-line)#loggin syn Router(config-line)#exit Router(config)#end Router#vlan database //建立vlan Router(vlan)#vlan 10 VLAN 10 added: Name: VLAN0010 Router(vlan)#vlan 20 VLAN 20 added: Name: VLAN0020 Router(vlan)#exit APPLY completed. Exiting.... Router#config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#interface f0/2 Router(config-if)#switchport access vlan 10 //劃分介面進vlan
Router(config-if)#interface f0/3 Router(config-if)#switchport access vlan 20 Router(config-if)#interface f0/1 Router(config-if)#switchport mode trunk //把連線路由器的介面封裝成trunk Router(config-if)#end |
2.分別配置pc1和pc2的IP地址
|
pc1(config)#interface f0/0 pc1(config-if)#no shut pc1(config-if)#ip add 172.16.0.1 255.255.255.0 pc1(config-if)#exit pc1(config)#ip default-gateway 172.16.0.254 //做單臂路由的實驗，pc需要指定預設閘道器 pc2(config)#interface f0/0 pc2(config-if)#no shut pc2(config-if)#ip add 192.168.0.1 255.255.255.0 pc2(config-if)#exit pc2(config)#ip default-gateway 192.168.0.254 |
3.在Router上配置單臂路由
|
Router>en Router#config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#no ip domain-lookup Router(config)#line console 0 Router(config-line)#no exec-timeout Router(config-line)#loggin syn Router(config-line)#exit Router(config)#interface f0/0 Router(config-if)#no shut Router(config-if)#exit Router(config)#interface f0/0.1 //進入f0/0的子介面 Router(config-subif)#encapsulation dot1q 10 //封裝dot1q，允許vlan10通過 Router(config-subif)#ip add 172.16.0.254 255.255.255.0 //配置閘道器地址 Router(config-subif)#exit Router(config)#interface f0/0.2 Router(config-subif)#encapsulation dot1q 20 Router(config-subif)#ip add 192.168.0.254 255.255.255.0 Router(config-subif)#end |
4.測試pc1能否ping通pc2
|
pc1#ping 192.168.0.1
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.0.1, timeout is 2 seconds: !!!!! //單臂路由可以實現不同vlan之間的通訊
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/36/76 ms pc2#ping 172.16.0.1
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 172.16.0.1, timeout is 2 seconds: !!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/38/64 ms |
