实验内容：
三层交换机具有路由功能，在一般三层交换都是需要手动开启其路由功能，

。只是神州的5526S交换机不用开启，可以直接使用。具体思路就是，在SwitchA上设置VLAN10，且VLAN10的IP地址为PC1的网关，另一半同理。（1）测试机配置
测试机PC1连接交换机A 1口，ip 192.168.10.1 网关：192.168.10.10
测试机PC2连接交换机B 10口，ip 192.168.20.1网关：192.168.20.10

SwitchA(Config-Vlan20)#interface vlan 20
SwitchB(Config-If-Vlan20)#ip address 192.168.20.10 255.255.255.0
SwitchB-Config[完整配置]
PC1<--->SwitchA(e0/0/1)
PC2<--->SwitchB(e0/0/10)
注意：PC2的网关并不是SwitchB上VLAN20的IP地址，而是SwitchA上的VLAN20的IP地址，并且在SwitchB上的VLAN20并未设置IP地址，因为意义不大，

（3）测试机A可以ping通测试机B。
实验要求：
掌握Vlan的定义,同一Vlan中的主机只要IP为同一网段便可以相互通信。
