BRIDGING AND ROUTING IN THE
C
OREBUILDER 2500 SYSTEM
This chapter describes how the CoreBuilder
™
2500 system operates in a
subnetworked routing environment and how the system’s bridging and
routing model compares with traditional models. The chapter contains
these topics:
■ What Is Routing?
■ Bridging and Routing Models
What Is Routing? Routing distributes packets over potentially dissimilar networks. A router
is the device that accomplishes this task. Routers typically:
■ Connect enterprise networks
■ Connect subnetworks (or client/server networks) to the main
enterprise network
Figure 3-1 shows where routers are typically used in a network.
CoreBuilder 2500 system routing connects subnetworks to the enterprise
network, providing connectivity between devices within a workgroup,
department, or building.
