You need to configure a router for a Frame Relay connection to a non-Cisco router. Which of the following commands will prepare the WAN interface of the router for this connection?
A
Router (config-if) #encapsulation frame-relay q933a
B
Router (config - if) #encapsulation frame-relay ansi
C
Router (config - if) #encapsulation frame-relay ietf
D
Router (config - if) #encapsulation frame-relay cisco
Correct Answer: Router (config - if) #encapsulation frame-relay ietf
If you have a Cisco router on one side of a Frame Relay network and a non-Cisco router on the otherside, you would need to use the Frame Relay encapsulation type of IETF. The default is Cisco encapsulation, which means that a Cisco router must be on both sides of the Frame Relay PVC.
