本实验需求:
通过在SW100 来创建VLAN 100 ,sw2 上创建VLAN 200,因为VLAN100和VLAN200因为业务上的关系,需要两台PC之间相互通信,保证不同VLAN之间可以互相访问。 本实验将给您详细阐述实现方法,将用到诸多交换知识点。
实验拓扑:
实验过程 第一步 SW100基础配置 SW100>
SW100>enable
SW100#conf t
Enter configuration commands, one per line. End with CNTL/Z.
SW100(config)#no ip do lo
SW100(config)#line con 0
SW100(config-line)#no exec-t
SW100(config-line)#logg syn
SW100(config-line)#exit
SW100(config)#username admin privilege 15 password admin
SW100(config)#line vty 0 15
SW100(config-line)#login local
SW100(config-line)#int f0/24
//配置把二层接口更改为三层接口
SW100(config-if)#no switchport
SW100(config-if)#ip add 12.0.0.1 255.255.255.0
00:02:57: %LINK-3-UPDOWN: Interface FastEthernet0/24, changed state to up
00:02:58: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/24, changed state to up
SW100(config-if)#no sh
第二步 SW200 基础配置 Switch>enable
Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#host SW200
SW200(config)#no ip do lo
SW200(config)#line con 0
SW200(config-line)#no exec-t
SW200(config-line)#logg syn
SW200(config-line)#exit
SW200(config)#username admin privilege 15 password admin
SW200(config)#line vty 0 15
SW200(config-line)#login local
SW200(config-line)#int f0/24
//把二层端口改变成三层接口
SW200(config-if)#no switchport
SW200(config-if)#ip add 12.0.0.2 255.2
00:03:40: %LINK-3-UPDOWN: Interface FastEthernet0/24, changed state to up
00:03:41: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/24, changed state to up
SW200(config-if)#ip add 12.0.0.2 255.255.255.0
SW200(config-if)#no sh
SW200(config-if)#exit
第三步 完整SW1上VLAN配置 //创建VLAN 100
SW100(config)#vlan 100
//给VLAN命名为100
SW100(config-vlan)#name 100
//进入f0/13接口模式下,把f0/13接口划分到VLAN100
SW100(config-vlan)#int f0/13
SW100(config-if)#switchport mode access
SW100(config-if)#switchport access vlan 100
SW100(config-if)#exit
SW100(config)#int f0/13
//因为此接口连接的终端设备,故可以关闭生成树的选举,开启快速端口特性
SW100(config-if)#spanning-tree portfast
%Warning: portfast should only be enabled on ports connected to a single
host. Connecting hubs, concentrators, switches, bridges, etc... to this
interface when portfast is enabled, can cause temporary bridging loops.
Use with CAUTION
%Portfast has been configured on FastEthernet0/15 but will only
have effect when the interface is in a non-trunking mode.
SW100(config-if)#exit
00:05:40: %SYS-5-CONFIG_I: Configured from console by console
//查看VLAN信息
SW100#show vlan brief

SW200(config-vlan)#int f0/15
SW200(config-if)#switchport mode access
SW200(config-if)#switchport access vlan 200
SW200(config-if)#exit
SW200(config)#int f0/15
SW200(config-if)#spanning-tree portfast
%Warning: portfast should only be enabled on ports connected to a single
host. Connecting hubs, concentrators, switches, bridges, etc... to this
interface when portfast is enabled, can cause temporary bridging loops.
Use with CAUTION
%Portfast has been configured on FastEthernet0/15 but will only
have effect when the interface is in a non-trunking mode.

第五步 在SW100上创建SVI(交换虚拟接口),并给SW100所连接PC配置IP地址为192.168.0.100,网关192.168.0.1(PC配置IP地址,网关,实验手册内容略过) SW100#conf t
Enter configuration commands, one per line. End with CNTL/Z.
//进入VLAN 100
SW100(config)#int vlan 100
//配置VLAN100,IP地址,这里的IP地址,就是F0/13接口下PC所指的网关地址
SW100(config-if)#ip add 192.168.0.1 255.255.255.0
SW100(config-if)#no sh
SW100(config-if)#end
00:06:09: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan100, changed state to up
//从SW100上测试可以ping通本VLAN下PC
SW100#ping 192.168.0.100
Type escape sequence to abort.

第七步 在SW100 上开启路由功能,并运行动态路由协议 SW100#conf t
Enter configuration commands, one per line. End with CNTL/Z.
//开启三层交换路由功能,默认是关闭的
SW100(config)#ip routing
SW100(config)#router ospf 100
SW100(config-router)#net 12.0.0.1 0.0.0.255 a 0

SW200#
第九步 在PC2 用ping命令测试到PC1,测试vlan200是否可以和VLAN 100 PING通,测试结果全网ping 通,实验现象成功(因为PC2是windows 7 简体中文版本,故ping结果是中文方式显示的) 测试步骤:开始-运行-cmd TABLE>
