VLAN Aggregation Configuration
This chapter describes how to configure VLAN aggregation. VLAN aggregation allows for communication between hosts on the same network segment that are in different VLANs. A network can conserve IP addresses with VLAN aggregation technology.
- Introduction to VLAN Aggregation
- Principles
VLAN aggregation defines the super-VLAN and sub-VLAN. A sub-VLAN is an independent broadcast domain that contains only physical interfaces. A super-VLAN contains no physical interface and is used for creating a Layer 3 VLANIF interface. By mapping a super-VLAN to sub-VLANs, VLAN aggregation associates the Layer 3 VLANIF interface with physical interfaces so that all sub-VLANs share one gateway to communicate with an external network. In addition, proxy ARP can be used to implement Layer 3 connectivity between sub-VLANs. - Application Scenario

VLAN aggregation can solve the problem of users from different VLANs being unable to communicate while still being able to access public network resources. - Configuration Examples
