单项选择题Refer to the exhibit. MPLS has been configured on all routers in the domain. In order for R2 and R3 to forward frames between them with label headers, what additional configuration will be required on devices that are attached to the LAN segment?（）

A.Decrease the maximum MTU requirements on all router interfaces that are attached to the LAN segment.
B.Increase the maximum MTU requirements on all router interfaces that are attached to the LAN segment.

D.No additional configuration is required. Frames with larger MTU size will be automatically fragmented and forwarded on all LAN segments.

单项选择题Refer to the exhibit. The show mpls interfaces detail command has been used to display information about the interfaces on router R1 that have been configured for label switching. Which statement is true about the MPLS edge router R1?（）

A.Packets can be labeled and forwarded out interface Fa0/1 because of the MPLS operational status of the interface.
B.Because LSP tunnel labeling has not been enabled on interface Fa0/1， packets cannot be labeled and forwarded out interface Fa0/1.
C.Packets can be labeled and forwarded out interface Fa1/1 because MPLS has been enabled on this interface.
D.Because the MTU size is increased above the size limit， packets cannot be labeled and forwarded out interface Fa1/1.
