The R1 (config-if)# Encapsulation frame-relay ietf is used to connect a Cisco router to a non-Cisco router.
Key Takeaway: The R1 (config-if)# Encapsulation frame-relay ietf uses the IETF encapsulation, instead of the default Cisco encapsulation. Additionally, in an actual configuration environment, some of the commands that follow this command specify the LMI used by the router to communicate with the Frame Relay switch.
