不同VLAN之间互访
不同VLAN之间互访
利用三层交换机实现不同VLAN之间的互访
交换机switch0和switch1创建4个vlan,vlan10,vlan20,vlan30,vlan40,将每个交换机的fa0/1-3,fa0/4-6,fa0/7-9,fa0/10-12分别分配给以上四个vlan，再在三层交换机上进行配置，要求实现不同vlan之间能够互访。
一、拓扑图
二、交换机的配置
1、switch0的配置
Switch>en
Switch#vlandatabase
Switch#conft
Enterconfigurationcommands,oneperline.EndwithCNTL/Z.
Switch（config）#interfacerangefa0/1-3
Switch（config-if-range）#switchportmodeaccess
Switch（config-if-range）#switchportaccessvlan10
Switch（config-if-range）#exit
Switch（config）#interfacerangefa0/4-6
Switch（config-if-range）#switchportmodeaccess
Switch（config-if-range）#switchportaccessvlan2
%AccessVLANdoesnotexist.Creatingvlan2
Switch（config-if-range）#switchportaccessvlan20
Switch（config-if-range）#exit
Switch（config）#interfacerangefa0/7-9
Switch（config-if-range）#switchportmodeaccess
Switch（config-if-range）#switchportaccessvlan30
Switch（config-if-range）#exit
Switch（config）#interfacerangefa0/10-12
Switch（config-if-range）#switchportmodeaccess
Switch（config-if-range）#switchportaccessvlan40
Switch（config-if-range）#exit
Switch（config）#interfacefa0/24
Switch（config-if）#switchportmodetrunk
Switch（config-if）#switchporttrunkallowedvlanall
Switch（config-if）#exit
Switch（config）#
2、switch1的配置
同switch0的配置一样
3、MultilayerSwitch0
Switch>enable
