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.full mesh of IBGP sessions
• B.mandatory creation of PE-to-PE BGP sessions between the outgoing interface IP addresses
• C.advertisement of extended communities, enabled on the PE-to-PE BGP neighbors
• D.full mesh of EBGP sessions and partial mesh of IBGP sessions
• E.creation of PE-to-PE BGP sessions between loopback IP addresses
• F.advertisement of standard communities, enabled on the PE-to-PE BGP neighbors

An ISP provides a major client MPLS VPN for managed services. The MPLS engineering team needs to use the advanced VPN feature of selective VRF import so that only specific prefixes are present in the required VPNs.
Which aspect of this feature must the team consider?

• A.A route is imported into the VRF only when at least one RT that is attached to the route matches one RT that is configured in the VRF and the route is permitted by the import route map.
• B.The import-map command is applied under the PE interface that connects to the CE router.
• C.A route must pass the import route map first and then the route target import filter.
• D.The routers that are imported in the VRF can be BGP and IGP routes, so other match conditions in the route map, besides communities, can be used.
