Question 13

Click on the exhibit button below.

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 14

Which of the following statements is NOT a valid reason to use MP-BGP as a routing protocol to transport VPRN routes?

The number of VPRN routes can become very large. MP-BGP can support a very large number of routes.

MP-BGP can carry routing information for a number of different address families.

MP-BGP is designed to exchange information between routers that are not directly connected. This feature keeps VPRN routing information out of P-routers.

MP-BGP can carry additional information attached to a route as an optional BGP attribute.

All of the above statements are valid reasons for using MP-BGP as a VPRN routing protocol.

Question 19

Which of the following statements best describes a route target?

A route target is a BGP extended community used to identify the VRF table for a prefix at the receiving PE

A route target is a mechanism from which VPRN controls the distribution of VPN routing information.

Route target attributes are earned in a MP-BGP as attributes of the route.

A route target is used by the PE router to identify the VRF that a VPN-lPv4 prefix is associated with.

All of the above statements describe a route target

None of the above statements describe a route target
