684 Chapter 9: Scenarios for Final Preparation
The Frame Relay configuration was relatively straightforward. The LMI type is autosensed.
The encapsulation of ietf between R1 and R4 is configured in two ways. First, R1 uses the ietf
keyword on the frame-relay interface-dlci command. On R4, the encapsulation command
lists the ietf option, implying ietf encapsulation for all VCs on this serial interface.
