 1. requirement

1. In each switch, create vlan2 and vlan3, And put it in the figure pc1、pc3、pc5 Divided into corresponding switches vlan2 in 、 take pc2、pc4、pc6 Divided into corresponding switches vlan3 in .
2. adopt DHCP Protocols are automatically assigned to computers ip Address .
3. It is required that data traffic can pass through the whole network .

 2. Topology

3. analysis ：

1.   According to the topology, the router is divided into three broadcast domains , Therefore, it is divided into 192.168.1.0/24;2.0/24;3.0/24 Three network segments of .
2. Because it is divided into two under the broadcast domain vlan, So divide the original network segment equally .
3. Both routers need to be turned on DHCP.
4. Network wide accessibility , You need to implement different vlan Interaction , And the setting of static route .

4. To configure ：

4.1. Switch configuration （vlan Division and setting trunk link ）：

•   Switch 1 Configuration of （ The other three are similar ）

4.2. Router r1 and r2 Configuration of （ Interface ip,DHCP, Static routing ）
