One 、VLAN polymerization

1、VLAN Aggregation is also called Super-VLAN, Use multiple... Within a physical network Sub-vlan Isolate broadcast area , speak Sub-Vlan Logically tied into one VLAN This VLAN It's super VLAN,Sub-VLAN Use the same IP Address subnet default gateway , Used to save IP Address resources .

2、Sub-VLAN, Contains physical interfaces , There will be no three layers VLANIF Interface , Used to isolate broadcast domain , So it's different Sub

-VLAN Interworking needs to pass Super-VLAN Three layers VLANIF Interface implementation

3、Super-VLAN No physical interfaces will be created , Super VLAN Create with Sub-Vlan Binding relationship

Two 、 Configuration requirements

1、 establish VLAN10、20 by Sub-VLAN 

2、 establish VLAN100 For super Super-VLAN

3、 Turn on Sub-VLAN To communicate with each other PC1 And P2 Can communicate with each other

4、 The terminal can realize the communication with the server

3、 ... and 、 Configuration to realize

1、SW1 And SW3 Create as an access switch VLAN

[SW1]vlan 10 // establish VLAN10

[SW1-GigabitEthernet0/0/1] port link-type access // The configuration interface is divided into access access

[SW1-GigabitEthernet0/0/1] port default vlan 10// The configuration interface belongs to vlan10

[SW1-GigabitEthe
