Although every device on a LAN is connected to every other device, they are not necessarily aware of each other's existence. To make services easier to be found and auto-configured throughout the network, modern printers, file servers, video streaming services, etc. allow to be auto-discovered. Auto-discovery is responsible for proactively informing every device on the same network about its presence by broadcasting auto-discovery information in regular intervals.
Clients need to be able to receive broad-casted auto-discovery information to benefit from auto-discovery. The way to configure your network to allow clients to receive this information depends on the specific use case. Usually, this is done using Bridge mode.

Auto-discovery facilitates finding and configuring services. Services with auto-discovery disabled can still be accessed but may require manual configuration.
