What is bridge connection in Linux?

Linux supports the implementation of a software network bridge to reproduce the function of a network bridge, a networking device that interconnects two or more communication networks or network segments providing a way for them to work as a single network.

How do you set up a bridge?

Here’s how to do it.

1. Position the bridge. Place the wireless bridge within range of your wireless router’s signal, and also within a cable’s length of your wired devices.
2. Connect the bridge to your network. If your router supports Wi-Fi Protected Setup, or WPS, setup is easy.
3. Plug in network devices.
