   Your AS has six BGP routers. You have configured Router R1 as a route reflector with clients R2, R3, and R4. Routers R5 and R6 are non-clients. R1 learns a route from R2 (a client). Which routers will R1 advertise this route to?

   • AOnly R3 and R4.
   • BOnly R5 and R6.
   • CNo routers, because of the iBGP split-horizon rule.
   • DR3, R4, R5, and R6.
