Which of the following about scaling techniques for route reflectors is FALSE?

Logical Partitioning of route reflectors works best when PEs are partitioned to support different VPRNs.

Logical Partitioning of route reflectors is simple and scalable, but requires more hardware.

Filtering at route reflectors requires either inbound filtering at the route reflector or outbound filtering at the PE routers.

Filtering at route reflectors allows the route reflector to filter routes received from PEs and only accept routes with a certain route distinguisher.
