IP Routing Protocols

INTERNETWORKING DIFFERENT LANS

Internetworking the same types of networks is a relatively simple operation. However, internetworking heterogeneous networks requires the IWU to assume additional and significant functions. Figure 4-21 shows the internetworking of an 802.3 LAN with an 802.5 LAN and lists some of the major differences that must be resolved by the IWU.

Internetworking different networks is not a trivial exercise. But the task can be accomplished if it is understood that an end user may not be able to achieve the full benefits of one or both of the internetworked protocols.
