NEW QUESTION # 45
What is the primary function of a VRF on a router?
- A. It enables the router to provide faster switching through the network by using labels to identify the input and output interfaces for neighbor routers.
- B. It enables the router to support multiple separate routing tables, which allows the device to handle overlapping IP addresses.
- C. It enables a router to configure VLANs locally, which provides segregation between networks.
- D. It enables a router to run BGP and a distance vector routing protocol at the same time, which allows it to serve as a VPN endpoint between remote sites.
Answer: B

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