- Router(config-if)# encapsulation frame-relay q933a
- Router(config-if)# encapsulation frame-relay ansi
- Router(config-if)# encapsulation frame-relay ietf
- Router(config-if)# encapsulation frame-relay cisco
Answer: Option 3
If you have a Cisco router on one side of a Frame Relay network and a non-Cisco router on the other side, 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 network.
