You work as a network designer for a company that is replacing their Frame Relay WAN with an
MPLS VPN service, where the PE-to-CE routing protocol is BGP. The company has 3000 routes in
their distribution routers, and they would like to advertise their access routers through the
MPLS network. Their service provider, however, only supports 1000 prefixes per VRF. Which
two design solutions can be applied to ensure that your access routers will be able to reach all
devices in your network? (Choose two.)

A.
Use prefix lists on your distribution routers to control which routes are sent to the MPLS
network.

B.
On your distribution routers, configure null routes and aggregate routes for the prefixes in
your network.

C.
Configure your distribution routers to send a default route to the MPLS network.

D.
Summarize the routes on the MPLS WAN interfaces of your distribution routers.
