Messid (Multiple Extended Service Set Identifier); Figure 4 Ap+Bridge Application - ZyXEL Communications G-3000 User Manual

Chapter 1 Introducing the ZyXEL Device
In the figure below, A and B use X as an AP to access the wired network, while X and Y
communicate in bridge mode.
When the ZyXEL Device is in AP+Bridge mode, you must use security for both the AP and
bridge functions, or for neither. However, the security the ZyXEL Device uses between APs
(the Wireless Distribution System or WDS) is different from the security between the wireless
stations and the AP. See
Unless specified, the term "security settings" refers to the traffic between the wireless stations
and the ZyXEL Device.
If you do not configure security in AP+Bridge mode, traffic between the
wireless stations and the APs and traffic between the APs is not encrypted.

1.2.4 MESSID (Multiple Extended Service Set IDentifier)

MESSID allows one access point to provide several ESSs simultaneously. It basically allows
the ZyXEL Device to provide several wireless networks with different wireless and security
settings. You can then assign varying levels of privilege to different wireless clients based on
the SSIDs they use.
