Bridge mode

As explained in Acing the CCNA Exam: Volume 2 Advanced Networking and Security

Bridge mode is a lightweight access point operational mode that forms wireless mesh links or bridges wired LANs across wireless connections.

Bridge mode configures a Cisco lightweight access point (LWAP) for mesh connectivity rather than direct wired attachment. LWAPs in this mode can form wireless links with other LWAPs or bridge two wired LANs across a wireless connection. section 19.3 section 19.2.2

Distinguish Bridge mode from the other client-serving LWAP modes:

  • Local mode is the default and provides BSSs while tunneling client traffic to the WLC through the CAPWAP data tunnel. section 19.2.2
  • FlexConnect locally switches client traffic between wired and wireless LANs, avoiding mandatory tunneling to the WLC and supporting per-SSID configuration. section 19.3
  • Flex + Bridge combines mesh connectivity with FlexConnect, allowing mesh LWAPs to locally switch client traffic instead of tunneling it to the WLC. section 19.3 section 19.2.2

Wireless bridge deployment

Place LWAPs where wiring every access point to the wired network is impractical. Configure them in Bridge mode so they form a wireless mesh; the same mode can connect two separate wired LANs over that mesh. section 19.3

How Acing the CCNA Exam: Volume 2 Advanced Networking and Security covers it

How deep it goes
Defines Bridge, Local, FlexConnect, and Flex + Bridge behavior but does not provide configuration commands or verification procedures.
Examples
Uses wireless meshes and bridges between two wired LANs as its concrete deployment examples.
What it assumes
Assumes familiarity with LWAPs, WLCs, client-serving modes, and CAPWAP-based traffic handling.
What you can do after
Evaluate LWAP operational modes and select Bridge or Flex + Bridge for mesh-based connectivity.
How it connects
Links Bridge mode with lightweight access points, wireless mesh, wired LANs, FlexConnect, WLCs, and CAPWAP.
