QUESTION 59
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 route must pass the import route map first and then the route target import filter.

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.

The import-map command is applied under the PE interface that connects to the CE router.

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.

PE1 labels the routes it learns from CE1 with the route-target 111:1 and shares them with its VPNv4 peers.

The PE-CE routes between the devices are being exchanged by OSPF

CE1 is supporting CSC.
