Which virtualization technique allows the same physical network devices to support multiple independent routing domains with separate routing tables?
Server virtualization
Containers
Virtual Routing and Forwarding (VRF)
Virtual LANs (VLANs)
Virtual Routing and Forwarding (VRF) enables a router to maintain multiple separate routing tables. This allows for network segmentation on a single physical router, supporting multiple virtual networks that operate independently. Server virtualization involves running multiple virtual machines on a single physical server, which pertains to servers and operating systems rather than routing tables. Containers share the host OS kernel and are used for application virtualization, not for network routing domains. Virtual LANs (VLANs) segment network traffic at Layer 2 (the data link layer), whereas VRFs operate at Layer 3 (the network layer).
