Question

An ISP delivers MPLS VPN managed services to a major client. The MPLS engineering team must use the advanced selective VRF-import feature so that only particular prefixes are present in the required VPNs. Which aspect of this feature must the team take into account?

Accepted Answer

D. 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.

Answer

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

Answer

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.

Answer

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