Which statement is true about the hardware requirements of MPLS?

A.
Because you do not need to run a routing protocol on P-routers, they require less memory than
routers
supporting classic IP routing.

B.
Because of the additional processing and memory requirements needed to build the LFIB,
MPLS is only available on high end routers.

C.
MPLS is available on low end routers, built their use is limited because of the additional
processing and memory requirements needed to build the LFIB.

D.
Because P-routers do not need to carry routes outside the MPLD domain, they require less
memory than routers that support the same application using classic IP routing.
