**Hello! I am a networking expert and I am happy to help you understand what a bridge router is.**

A bridge router is a networking device that connects two or more networks together. It operates at the data link layer of the OSI model, which means that it is responsible for forwarding data between networks based on their MAC addresses.

Bridge routers are often used to connect LANs (local area networks) to WANs (wide area networks). They can also be used to connect two or more LANs together.

Bridge routers work by forwarding data frames between networks. When a data frame arrives at a bridge router, the bridge router examines the frame's MAC address and determines which network the frame should be forwarded to. The bridge router then forwards the frame to the appropriate network.

Bridge routers are transparent to the devices on the networks that they connect. This means that the devices on the networks do not need to be aware of the existence of the bridge router.

**Here are some of the benefits of using bridge routers:**

* They can be used to connect multiple networks together, allowing devices on different networks to communicate with each other.
* They can be used to segment large networks into smaller, more manageable networks.
* They can be used to improve network performance by reducing congestion.

**Here are some of the limitations of using bridge routers:**

* They can only be used to connect networks that use the same MAC address format.
* They can introduce latency into a network, which can slow down network performance.
* They can be security risks, as they can allow unauthorized devices to access a network.

Overall, bridge routers are a versatile and useful networking device that can be used to improve network performance and security.

When your network will contain more than one router, select bridge mode for each of the additional routers if they will be connecting to a router or other network device that is already using DHCP and NAT to provide IP addresses to computers on your network.read more >>
