Once the packet is received by the Router A, attached to LAN 1, it strips 

 

off the network header (refer to 

 

 

) and examines the Layer 3 

 

datalink header information. It then reviews its routing tables in order 

 

to establish where to forward the data packet. It is possible that the 

 

LAN 1 router has multiple outgoing ports that would allow different 

 

transmission routes to the destination network. In our example using 

 

 

, a packet could go via Router D to get to Router B, or it 

 

could go more directly across a single direct link between Router A and 

 

Router B.

 

 

Data Packet Containing Hardware And Software Addresses

 

 

The local router contains, within its routing table, information which 

 

will allow it to determine the best data transmission route. The type of 

 

information the router uses to make these assessments is protocol 

 

dependent, and some communications protocols may employ a range 

 

of routing algorithms, and accompanying routing protocols. In the case 

 

of the TCP/IP protocol suite, the AccessBuilder 500 utilizes the Routing 

 

Information Protocol (RIP). RIP is also known as a 

 

 

 

protocol.
