Configuration Examples

This section shows examples of configuring the switch functions on the router.

All examples assume that the switch configuration begins from factory default

settings.

Note that routing, required for communication between the VLANs, is not

shown in these examples.

Example using one router to extend a local LAN

The example in Figure 3-4 on page 3-18 uses a single router to connect two (or

more) physical LANs and a server. All devices connected to the router belong

to the same broadcast domain, and separate collision domains. The Learning

and Forwarding Processes in the router give this topology better performance
