What is LAN to LAN (LAN 2 LAN)?

LAN to LAN connection (LAN 2 LAN) connects one Ethernet port (LAN port) of a primary router to a LAN port on a secondary router. The term is also known as cascading.

The process aims to increase a network's range and reduce the number of devices communicating with a single router. A device connects to the router with the strongest signal and does not disconnect when moving between routers.
