Overview Super-VLAN

Different VLANs are isolated from each other at layer 2. To enable them to communicate with each other, you must configure a VLAN interface and IP address for each VLAN. However, this mode consumes a large number of scarce IP address resources. Super- VLAN, also called VLAN aggregation, can solve this problem effectively. A common VLAN, after being added into a super-VLAN, becomes a sub-VLAN of the super-VLAN. If the Address Resolution Protocol (ARP)/ND proxy function is enabled for the super-VLAN, the super-VLAN shares its VLAN interface with its sub-VLANs. In this way, the sub-VLANs take the VLAN interface IP address of the super-VLAN as the gateway to implement layer- 3 communication. This saves IP/IPv6 address resources.
