3.4.2 Super VLAN Supporting DHCP Relay Example

I. Network requirements

Create VLAN 6 and configure it as a super VLAN, and create VLAN 2 and VLAN 3

as the sub VLANs which map with VLAN 6.

Configure the IP address of the VLAN 6 as 10.1.1.1, and the sub network mask as

255.255.255.0.

Enable the DHCP relay function on the VLAN interface of VLAN 6, and establish

the mapping between VLAN 6 and the remote DHCP server group 2 to make the

hosts in VLAN 2 and VLAN 3 be able to dynamically obtain IP addresses from the

DHCP server group 2.

II. Configuration Procedure

# Create VLAN 6, and configure it as a super VLAN.

<H3C> system-view

[H3C] vlan 6

[H3C-vlan6] supervlan

# Create VLAN 2 and VLAN 3 and establish the mapping between them and VLAN 6.

[H3C-vlan6] vlan 2

[H3C-vlan2] vlan 3

[H3C-vlan3] vlan 6

[H3C-vlan6] subvlan 2 3

# Create the VLAN interface of VLAN 6, and configure an IP address for it.

[H3C-vlan6] interface Vlan-interface 6

[H3C-Vlan-interface6] ip add 10.1.1.1 255.255.255.0

# Enable the DHCP relay function on the VLAN 6 interface, that is, establish the

mapping between the interface and the DHCP server group 2.
