Multiple Basic Service Set ID (MBSSID)

- [Instructor] An access point has the ability to advertise more than one SSID. For example, on screen we have each access point advertising both a KWTRAIN SSID, in addition to a KWGUEST SSID. And as we mentioned earlier, a wireless access point can roam around a building and connect to an appropriate access point, while remaining on the same wireless network. And that was possible because each access point had a unique MAC address corresponding to a wireless network. And that unique MAC address was called the basic service set identifier, or the BSSID. Well in this example, since each access point has more than one SSID, each access point also has more than one MAC address. They have more than one BSSID. That's where we get the term multiple basic service set ID, or MBSSID. It's an access point servicing more than one wireless network or SSID, each with its own unique MAC address.
