Note

 

Bridges vs. Routers :

 The essential difference between a bridge 

and a router is that a router uses a higher-level protocol (such as  
IP) to determine how to pass data. IP data packets contain IP 
addresses that specifically identify the destination computer. 
Routers can read this information and pass the data to the 
destination computer, or determine which next router to send the 
data to if the destination is not on a connected network. 

Bridges cannot read IP information, but instead refer to the 
hardware ID of the destination computer, which is also included in 
data packets. The hardware ID is a unique number that the 
manufacturer assigns to each piece of hardware it sells. A bridge 
learns to recognize the hardware IDs accessible through each of 
its ports. When it receives a packet, the bridge simply forwards the 
packet through the port it associates with the given hardware ID, 
or through all its ports if it does not recognize the ID. The 
hardware ID is often referred to as the 

Media Access Control 

(MAC) address.

 

Routers are considered more intelligent and flexible devices than 
bridges, and often provide a variety of security and network 
administration services based on the IP protocols. 

Using the Bridging Feature 

Although the Neobit 1012VAis pre-configured to serve as a router 
for providing Internet connectivity to you LAN, there are several 
instances in which you may also want to configure bridging: 

 

Your ISP may use protocols that require bridging with your 
LAN. The device can be configured to appear as a bridge 
when communicating with your ISP, while continuing to 
provide router functionality for your LAN. 

 

Your LAN may include computers that communicate using 
“layer-3” protocols other than the Internet Protocol. These 
include IPX

®

 and AppleTalk

®

. In this case, the device can 

be configured to act as a bridge for packets that use these 
protocols while continuing to serve as a router for IP data. 

In both cases, you need to specify the device’s interfaces as bridge 
interfaces.
