Border Gateway Protocol Fundamentals for Services

Which statement below about route reflectors is FALSE?

  • A A full iBGP mesh is required among route reflectors.
  • B A route reflector can have both iBGP and eBGP clients.
  • C A router reflector disables the iBGP split-horizon rule for its clients.
  • D Route reflectors are used to reduce the number of iBGP sessions required in an AS.
Explanation

A route-reflector client is an iBGP router. eBGP neighbors can advertise routes to a route reflector, but they are not route-reflector clients; therefore, a route reflector cannot have eBGP clients. Route reflection relaxes the usual iBGP advertisement restriction for client relationships and reduces the need for a full mesh of iBGP sessions within an AS.
