先决条件 – 网络设备
网桥是网络设备，工作在数据链路层。通过网桥，数据或信息以数据包的形式存储和发送。而路由器也是工作在网络层的网络设备。通过路由器，数据或信息以数据包的形式存储和发送。
网桥和路由器的主要区别在于，网桥研究或扫描设备的 MAC 地址。另一方面，路由器研究或扫描设备的 IP 地址。
让我们看看下面给出的网桥和路由器之间的区别：
| S.NO | Bridge | Router |
|---|---|---|
| 1. | Bridge works in data link layer. | While Router works in network layer. |
| 2. | Through bridge, data or information is not store and sent in the form of packet. | While through router, data or information is store and sent in the form of packet. |
| 3. | There are only two ports in bridge. | While there are more than two ports in router. |
| 4. | Bridge connects two different LANs. | While router is used by LAN as well as MAN for connection. |
| 5. | In bridge, routing table is not used. | While in routers, routing table is used. |
| 6. | Bridge works on single broadcast domain. | While router works on more than single broadcast domain. |
| 7. | Bridges are easy to configure. | While Routers are difficult to setup and configure. |
| 8. | Bridge focuses on MAC address . | While Router focuses on protocol address. |
| 9. | Bridge is comparatively inexpensive. | While Router is relatively expensive device. |
| 10. | Bridges are good for segment network and extends the existing network. | While Routers are good for joining remote networks. |
