router vs bridge | difference between router and bridge
This page compares router vs bridge describes difference between router and bridge. The major difference between router and bridge is that router links all forms of LANs where as bridge links same type of LANs.
| router | bridge |
|---|---|
| It uses software configured network address(ip address) to determine the address. | It determines the destination address with the help of MAC address(i.e. ethernet address) of the device. |
| The router devices use the routing tables to route the data to the destination. | The bridge devices do not use any other device to transfer the data to the destination. |
| Router devices communicate with other routers to decide(select) the best path to transfer the data. | With the help of MAC addresses of the devices connected in the network, the bridges listen to the network traffic and then decide the best path to send the data. |
| Router devices are used to connect the LAN and WAN links. | Bridge devices are used to connect the LAN links. |
| Bandwidth Utilization: Optimized for traffic loading across the entire network. | Fixed by "Spanning Tree Algorithm or Source Routing". |
| WAN access: Possible to construct a complex mesh of point-to-point links. | Usually single port |
| Management:Statistics about specific protocols. | Statistics about frames and bridge operations. |
| Performance:Similar to bridges but can limit traffic from sources by quenching. | May suffer in heavy traffic environments. |
| Routing Protocol examples: TCP/IP, IPX/SPX, Apple Talk | Types of bridges include transparent bridge and translational bridge. |
