  Two 、 experiment ：

  Simulator ：Cisco Packet Tracer

（１） Experimental thinking ：

• PC Configure separately ＩＰ And gateway
• 1. The access switch creates corresponding data vlan,
• 2. Mark the interface into the corresponding vlan in
• 3. Encapsulate the interface connecting the router trunk
• 4. The router turns on the parent interface
• 5. The router creates two sub interfaces , Configure the gateway separately and correspond to the gateway vlan binding

（２） The topology ：

 

(3) Experiment related configuration ： 

• —— Access switch ：

vlan 10  - ------ establish vlan name vlan
name PC1
vlan 10
name PC2

int f0/1---- Access interface
switchport mode access  ----- Set the interface to access mode
swtichport access vlan 10   ------ Draw the interface into vlan10
exit

int f0/3  ---- Access interface
switchport mode trunk  ------ encapsulation trunk
exit

• —— Router router：

int f0/0---- Access interface
no shutdown ----- Open the interface
exit
int f0/0.10  ---- Enter sub interface
 encapsulation dot1Q 20---- Connecting sub interfaces to vlna 20 binding
 ip address 192.168.20.254 255.255.255.0 --- To configure ip Address as PC gateway
no shutdown --- Open the interface

—— The router creates sub interfaces ：

notes :

• Check the interface IP And state ：show ip interface brief
• View routing table ：show ip route
