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

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

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

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

A CE1 system interface can not be advertised to PE2 since the CE routers are not aware of the VPRN.

Question 10

Click the exhibit.

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

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

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

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

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