Refer to the exhibit. A router interface is being configured for Frame Relay. However, as the
exhibit shows, the router will not accept the command to configure the LMI type. What is the
problem?
A.
The interface requires that the encapsulation frame-relay command be configured first.
B.
The interface does not have an IP address assigned to it yet.
C.
The interface does not support Frame Relay connections.
D.
The interface requires that the no shutdown command be configured first.
Explanation:
Before entering LMI type in interface, you should type the encapsulation frame-relay command.
By default, serial interfaces use HDLC encapsulation, where the LMI type is not a configurable
option as HDLC does not understand the concept of LMI.
See the sample Configuration steps:
Router(config-if)#encapsulation frame-relay {cisco | ietf}
Router(config-if)#frame-relay lmi-type {ansi | cisco | q933a}
