3.1 Overview of Super VLAN
To save IP address resources, the super VLAN concept (also known as VLAN
aggregation) was developed. Its principle is like this: a super VLAN may include
multiple sub VLANs (as subnets), with each as a broadcast domain. The super VLAN
can be assigned with an IP address, but not the sub VLAN. Layer 2 isolation is
implemented between sub VLANs. When users in different sub VLANs want Layer 3
communication, they use the IP address of the super VLAN as their gateway address.
IP address resources are saved since multiple VLANs share one IP address. ARP
proxy enables Layer 3 interworking between sub VLANs and their interworking with
other networks by forwarding and handling ARP request and response packets.
