Point-to-Point Wireless Bridging

Mesh access points can support a point-to-point bridging application. In this deployment, mesh access
points extend a Layer 2 network by using the backhaul radio to bridge two segments of a switched
network (see
LAN clients.
Client access can be provided with Ethernet bridging enabled, although if bridging between buildings,
MAP coverage from a high rooftop might not be suitable for client access.
If you intend to use an Ethernet bridged application, you must enable the bridging feature on the RAP
and on all MAPs in that segment. Also verify that any attached switches to the Ethernet ports of your
MAPs are not using VLAN Trunking Protocol (VTP). VTP can reconfigure the trunked VLANs across
your mesh and possibly cause a loss in connection for your RAP to its primary WLC. If improperly
configured, it can take down your mesh deployment.

Point-to-Multipoint Wireless Bridging

Mesh access points support point-to-multipoint bridging applications. Specifically, a RAP acting as a
root bridge connects to multiple MAPs as non-root bridges with their associated wired LANs. By
default, bridging is disabled for all MAPs. If Ethernet bridging is used, you must enable it on the
controller for the respective MAP and for the RAP. Refer to the
Ethernet VLAN Tagging" section on page 8-25
