Virtual Access Point Layer 2 Bridge
The Virtual Access Point (VAP) Layer 2 Bridge feature enables network administrators to bridge a wireless interface zone to a wired interface zone. The VAP Layer 2 Bridge is based on the WLAN Layer 2 bridge and the wireless VAP and makes it much easier to deploy a combined wireless and wired network.
All devices on a VAP Layer 2 Bridge share the same subnet and can forward broadcast packets. On a wired interface Layer 2 Bridge, all packets with VLAN tags are forwarded to the bridge-partner interface (the interface with the same VLAN address).
A VLAN subinterface does not support Layer 2 Bridge mode. However, the VAP Layer 2 Bridge feature supports Layer 2 bridges for subinterfaces when the interface zone is a WLAN zone.
When a VAP Layer 2 Bridge is configured, wireless clients on VAP interfaces share the same subnet with the primary bridge interface.
