三层交换的配置
实验拓扑图：
实验要求：
配置三层交换机，实现不同vlan之间的通信。
实验过程
1.pc1的预配置
|
Router>en Router#config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#host pc1 pc1(config)#no ip routing //路由器模拟pc需要关闭路由功能 pc1(config)#interface f0/0 pc1(config-if)#no shut pc1(config-if)#ip add 192.168.1.1 255.255.255.0 pc1(config-if)#exit pc1(config)#ip default-gateway 192.168.1.254 //三层交换需要pc指定网关 pc1(config)#end |
2.pc2的预配置
|
Router>en Router#config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#host pc2 pc2(config-if)#no ip routing pc2(config)#interface f0/0 pc2(config-if)#no shut pc2(config-if)#ip add 192.168.2.2 255.255.255.0 pc2(config-if)#exit pc2(config)#ip default-gateway 192.168.2.254 pc2(config)#end |
3.在sw1上创建vlan10和vlan20，并把f0/1划分进vlan10，f0/2划分进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)#hos sw1 sw1#vlan database sw1(vlan)#vlan 10 //创建vlan VLAN 10 modified: sw1(vlan)#exit APPLY completed. Exiting.... sw1#vlan database sw1(vlan)#vlan 20 VLAN 20 modified: sw1(vlan)#exit APPLY completed. Exiting.... sw1# sw1#config t Enter configuration commands, one per line. End with CNTL/Z. sw1(config)#interface f0/1 sw1(config-if)#switchport access vlan 10 //划分接口进相应的vlan sw1(config-if)#interface f0/2 sw1(config-if)#switchport access vlan 20 sw1(config-if)#exit |
4.在sw1上配置三层交换
|
sw1(config)#interface vlan 10 sw1(config-if)#ip add 192.168.1.254 255.255.255.0 //给vlan添加IP地址 sw1(config-if)#no shut sw1(config-if)#exit sw1(config)#interface vlan 20 sw1(config-if)#ip add 192.168.2.254 255.255.255.0 sw1(config-if)#no shut sw1(config-if)#end |
5.查看sw1上vlan信息
|
sw1#show vlan-sw br
VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Fa0/0, Fa0/3, Fa0/4, Fa0/5 Fa0/6, Fa0/7, Fa0/8, Fa0/9 Fa0/10, Fa0/11, Fa0/12, Fa0/13 Fa0/14, Fa0/15 10 VLAN0010 active Fa0/1
20 VLAN0020 active Fa0/2
1002 fddi-default active 1003 token-ring-default active 1004 fddinet-default active 1005 trnet-default active |
6.测试两台pc的连通性
|
pc1#ping 192.168.2.2
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.2.2, timeout is 2 seconds: !!!!! //三层交换可以实现不同vlan之间的通信
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/42/76 ms pc2#ping 192.168.1.1
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds: !!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/32/44 ms |
