  A. The customer announces the public IP subnet to the ISP The ISP announces the default route to the customer

  B. The customer announces the public IP subnet to the ISP The ISP announces the BGP table to the customer

  C. The ISP announces the customer public IP subnet The ISP announces the partial BGP table to the customer

  D. The customer announces the default route to the ISP The ISP announces the default route to the customer
