• Question 24:

  Which two statements about MPLS L3 VPN RDs are true? (Choose two.)

  A. They enable EIGRP to use address families to separate traffic between IPv4 and VPNv4.

  B. They are represented as 32-bit values

  C. They are represented as 64-bit values.

  D. They enable OSPF to import and export routes into the global routing table of a router.

  E. They allow BGP to uniquely identify duplicate routes.

  Correct Answer: CE

• Question 25:

  Which is the primary function of a MPLS L3 VPN route target?

  A. It imports and exports identified routes into selected VRFs.

  B. It uniquely identifies NLRIs that have the same numeric value.

  C. It imports the external routes it identifies into VRFs that support Internet traffic

  D. It supports QoS by classifying traffic by file type when it applies MPLS EXP bits to each packet.

  Correct Answer: A

• Question 26:

  You are writing the requirements for an MPLS L3VPN environment that uses MP-BGP between PE routers. In this environment, route targets and route distinguishers need to be advertised between the PE routers.

  Which three operations meet these requirements? (Choose three.)

  A. mandatory creation of PE-to-PE BGP sessions between the outgoing interface IP addresses

  B. advertisement of standard communities, enabled on the PE-to-PE BGP neighbors

  C. creation of PE-to-PE BGP sessions between loopback IP addresses

  D. full mesh of IBGP sessions

  E. full mesh of EBGP sessions and partial mesh of IBGP sessions

  F. advertisement of extended communities, enabled on the PE-to-PE BGP neighbors

  Correct Answer: CDF

  C. R1 mutually redistributes routes between BGP 65001 and the OSPF process of VRF custabc.

  D. R1 redistributes BGP routes into the OSPF process of VRF custabc as OIA routes.

  Correct Answer: A
