The figure shows an example of how to configure the voice-adaptive feature and end-to-end fragmentation on the interface. The only difference between this figure and the previous figure is that end-to-end fragmentation on the previous figure was configured on the interface, and in this example the fragmentation is enabled by being embedded within the Frame Relay map class.
