a VPRN forwards data packets at the network layer. To enable this, each VPN node on the public network must establish a dedicated VPN routing and forwarding table (VRF) that contains network-layer reachability information for each VPN. These dedicated VRFs guide the forwarding of data flows bet...
VRF names enable organizations to use IP address space multiple times among isolated routing domains. Each customer has its own IP VRF so that overlapping subnets are kept isolated from one another. With a route distinguisher, RD value for short, each default route is made different -- or dist...

Virtual routing and forwarding (VRF) is a technology within IP based routers that enables them to create and operate multiple instances of a routing table simultaneously. VRF enables a router to create multiple instances of router within it, each of which operates separately and has its distinct ...
Often presented assoftware-defined networking (SDN)for the WAN, SD-WAN is arguably the most widely deployed use case in SDN. Cisco notes that the SDN paradigm “became popular for abstracting network infrastructure in the data center and other sections within the enterprise perimeter.” SD-WAN ...
