A network engineer needs to configure a single router to support multiple customers, ensuring that each customer's routing information remains separate and secure. Which technology should the engineer implement to meet this requirement?
Virtual LANs
Virtual Routing and Forwarding
Network Address Translation
Containerization
Virtual Routing and Forwarding (VRF) allows a router to maintain multiple separate routing tables, effectively segmenting the network traffic and keeping each customer's routing information isolated. This enables multiple instances of a routing table to co-exist on the same router without interference. Virtual LANs (VLANs) segment Layer 2 networks but do not separate routing information at Layer 3. Network Address Translation (NAT) translates IP addresses but does not provide routing table isolation. Containerization is a virtualization method for applications, not for routing configurations on network devices.
