Objective:

DHCP automatically assigns addresses

2. Inter-VLAN communication

Experimental procedure:

Create vlan [sw1 vlan10 sw2 vlan20] on two layer 2 switches and add three ports to the corresponding vlan

[sw1]vlan 10

[sw1-vlan10]q

[sw1-GigabitEthernet0/0/1]undo sh

Info: Interface GigabitEthernet0/0/1 is not shutdown.

[sw1-Ethernet0/0/1]port link-type acc//Select access mode

[sw1-Ethernet0/0/1]port def vlan 10 //join vlan10

The same applies to other ports [SW2 only changes vlan10 to vlan20] Configure Layer 3 switches:

Create vlan10, 2

Add vlan10/20 to port [access mode]

Configure vlanIP:

[dhcp-Vlanif10]undo sh

Info: Interface Vlanif10 is not shutdown.

[dhcp-Vlanif10]

[dhcp-Vlanif10]ip add 192.168.10.254 255.255.255.0

[dhcp-Vlanif20]ip add 192.168.20.254 255.255.255.0

Create an address pool:

[dhcp]ip pool vlan-10

Info:It's successful to create an IP address pool.

[dhcp-ip-pool-vlan-10]network 192.168.10.0 mask 255.255.255.0

[dhcp-ip-pool-vlan-10]gateway-list 192.168.10.254

[dhcp]ip pool vlan-20

Info:It's successful to create an IP address pool.

[dhcp-ip-pool-vlan-20]network 192.168.20.0 mask 255.255.255.0

[dhcp-ip-pool-vlan-20]gateway-list 192.168.20.254

DHCP enabled, port enabled DHCP Global:

[dhcp]dhcp enable

Info: The operation may take a few seconds. Please wait for a moment.done.

[dhcp-Vlanif10]dhcp select global

[dhcp-Vlanif20]dhcp select global

configuration complete

3. Verification, testing, preservation
