Scene description:

The company has three departments, Finance, sales and it, which use vlan10, vlan11 and vlan12 respectively, requiring that all departments can visit each other.

The principle of implementation:

The three departments are located in different vlan and different access switches. In order to access each other, inter-vlan routing must be used and a layer 3 device is needed. In this experiment, layer 3 switching is used for routing, and vlan data access across the switch needs to communicate in the relay channel by forwarding to the corresponding port of the switch.

Configuration steps:

1 basic configuration: create vlan and divide ports (take it switch as an example)

Create a vlan on each switch and associate it with a port (similar to other switch configurations)

Switch (config) # vlan 10

Switch (config) # vlan 100

Switch (config-vlan) # vlan 11

Switch (config-vlan) # vlan 12

Switch (config-vlan) # vlan 13

Switch (config) # int f0bin2

Switch (config-if) # switch

Switch (config-if) # switchport mode access

Switch (config-if) # switchport access vlan 10

2 configure the switch trunk port and configure the management address

Switch (config) # int f0amp 22

Switch (config-if) # switchport mode trunk

Switch (config-if) # switchport trunk allowed vlan all

Switch (config) # int vlan 100

Switch (config-if) # ip address 10.100.50.11 255.255.255.0
