Wireless BridgesWireless Bridges
A wireless bridge provides connectivity between two wired LAN segments.
A wireless bridge is a half-duplex device capable of layer 2 wireless connectivity only.
Wireless Bridge ModesWireless Bridge Modes
Root ModeNon-root ModeAccess Point ModeRepeater Mode
Root ModeRoot Mode
A root bridge can only communicate with non-root bridges and other client devices and cannot associate with another root bridge.
NonNon--root Moderoot Mode
Wireless bridges in non-root mode attach, wirelessly, to wireless bridges that are in root mode.
Access Point ModeAccess Point Mode
Actually just giving the bridge access point functionality.
