Switching routing (VLAN) experiment

step 1： analysis  

1、 It can be seen from the picture that pc1 and pc3 The interface is access Interface , And divided into VLAN2 in , Given a network segment 192.168.1.0/24, Router r1 Set sub interface management pc1 and pc3, And set... For the sub interface dhcp send ip Automatic access to

2、pc2、4、5、6 In the same network segment , among pc2 Divide VLAN3,pc4、5 Divide VLAN4,pc6 Divide vlan5, Use hybrid mode to configure pc With the switch VLAN

3、pc2 The interface connecting the switch allows VLAN3 Up ,VLAN3、4、5 Peel off the label and come down

4、pc4 The interface connecting the switch allows VLAN4 Up ,VLAN3、4 Peel the label off

5、pc5 The interface connecting the switch allows VLAN4 Up ,VLAN3、4 Peel the label off

6、pc6 The interface connecting the switch allows VLAN5 Up ,VLAN3、5 Peel the label off

7、sw1 and sw2 Configuration between trunk main rd ,sw2 and sw3 Mixed trunk roads are arranged between

8、r1 and sw1 You can put pc2、4、5、6 as VLAN1, Therefore, mixed trunk roads are provided

step 2： Build simulation diagram

step 3： Create... On the switch VLAN, And switch the interface to VLAN

step 5：pc End automatic access ip Address

step 6： test

1、pc1 You can visit pc2、3、4、5、6

2、pc2 You can visit pc4、5、6

3、pc4 You can visit pc5, Cannot access pc6

4、pc5 Cannot access pc6
