Is a routing policy required on PE1 to advertise a CE1's system interface to PE2?

A. Yes. A routing policy is required to advertise routes between PE routers in a VPRN

B. No. A routing policy is not required; the default behavior on the Nokia 7750 SR is to advertise all VPRN routes between PE routers.

C. A routing policy is required only when BGP is used as the PE-CE routing protocol, as shown in the exhibit.
