Referring to the exhibit, routers R1 through R5 exist in a fully-meshed IBGP group. You want the
routes received through EBGP on R1 to be advertised to the EBGP peer connected to R5. You want the routes received through EBGP on R5 to be installed on R1; however, you do not want the those routes to be advertised to the EBGP peer connected to R1.
Which two actions will accomplish this task? (Choose two.)
A. Implement a route reflector group and configure the no-client-reflect parameter on the route reflector.
B. Implement an import policy on R1 to add the well-known no-export community to the EBGP routes.
C. Implement an export policy on R5 to add the well-known no-advertise community to the EBGP routes.
D. Implement an export policy on R5 to add the well-known no-export community to the EBGP routes.
