Configuring Point-to-Point Subinterfaces

The second sample network, based on the environment shown in Figure 14-5, uses point-to-point subinterfaces. Point-to-point subinterfaces work well when the subnetting design calls for one subnet for each PVC. Examples 14-8 through 14-11 show the configuration for this sample network, with all four routers using only point-to-point subinterfaces. Pay close attention to the command prompts in Example 14-8, because they change when you configure subinterfaces.
