新しい質問45
What is the primary function of a VRF on a router?

 It enables the router to support multiple separate routing tables, which allows the device to handle overlapping IP addresses.

 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.

 It enables a router to configure VLANs locally, which provides segregation between networks.

 It enables the router to provide faster switching through the network by using labels to identify the input and output interfaces for neighbor routers.
