Pramati Technologies WaveMaker. Virtual routing and forwarding (VRF) is a technology included in IP (Internet Protocol) network router s that allows multiple instances of a routing table to exist in a router and work simultaneously. This increases functionality by allowing network paths to be segmented without using multiple devices.
Within a VPN, each site can send IP packets to any other site in the same VPN. Each VPN is associated with one or more VPN routing or forwarding instances (VRFs). A VRF consists of an IP routing table, a derived Cisco express forwarding (CEF) table, and a set of interfaces that use this forwarding table.
