This article will explain how to create a bridged interface on an EdgeRouter. Bridged interface are used to place multiple physical ports on the same LAN, similar to how a switch functions.

Generally, it is not recommended to bridge ports as it will greatly reduce the performance.  If multiple ports need to be placed on the same LAN, it is advisable to use a router with a build-in switch-chip such as the ER-X, ER-X-SFP, EP-R6 or ERPoE-5.
