A Large Enterprise Company Is Redesigning Their WAN Infrastructure and Has

A large enterprise company is redesigning their WAN infrastructure and has these design requirements: The Frame Relay WAN infrastructure will be replaced with an MPLS VPN service. BGP is the PE-CE routing protocol adopted for this scenario. There are 3000 routes in the routing database of the distribution routers. All 3000 routes will be advertised from the access routers through the MPLS network. The service provider that provides this MPLS VPN service supports only 1000 prefixes per VRF. Which two design solutions ensure that the enterprise access routers reach all devices in this enterprise network? (Choose two.)

A) Use prefix lists on the distribution routers to control which routes are sent to the MPLS network
B) Configure the distribution routers to send a default route to the MPLS network
C) Configure null routes and aggregate routes for the prefixes in your network on the distribution routers
D) Configure the access routers to send a default route to the MPLS network
E) Summarize the routes on the MPLS WAN interfaces of the distribution routers
