  Routes are exchanged between CE1 and PE1 using BGP. CE2 and PE2 use static routes to forward traffic to and from the VPRN. Which of the following is FALSE?

  A. An export policy is required on PE1 to advertise routes to CE1.

  B. An export policy is required on CE1 to advertise local routes to PEL

  C. An export policy is required to advertise routes between the PE routers.

  D. No export policy is required on PE2 or CE2 due to the static routes.

  Assuming CE1 exports its system address using BGP, is a routing policy required on PE1 to advertise CE1's system address to PE2?

  A. Yes, A routing policy is required to advertise routes between PE routers in a VPRN regardless of the CE-PE routing.

  B. Yes, A routing policy is required in this case because BGP is used as the PE-CE routing protocol.

  C. No, a routing policy is not required. By default, the Alcatel-Lucent 7750 SR will advertise all VPRN routes between PE routers.

  D. No, a routing policy is not required on PE1, but an import policy is required on PE2.
