Bridges operate at Layer 2, the Ethernet layer. The kernel's bridge module maintains MAC address forwarding tables. When frames arrive on eth0, the bridge searches destination MAC addresses in this table, forwarding frames to ports where addresses were last observed. For unknown addresses, bridges flood frames to all member ports. Bridge-expired learned associations follow configurable aging timers. To remaining networks, br0 appears as unified switching equipment, shared Layer 2 segments across both wired and wireless interfaces. The kernel implements bridge forwarding logic in br_forward() within net/bridge/br_forward.c.
