Interworking on Different Network Segment
As shown in Figure 9-10, as businesses of Enterprise A develop, data communication is required
between departments of Enterprise A, and between Enterprise A and local Enterprises B.
Departments of Enterprise A belong to the LANs on the same network segment, and therefore
they can be bridged to communicate with each other. Enterprise B, however, belongs to a LAN
on a different network segment. Therefore, link-layer bridging cannot meet the requirement of
the communication between Enterprise A and Enterprise B.
In this case, you can configure local bridging integrated with IP routing to achieve the
communication between Enterprise A and Enterprise B.
