VRF: VPN Routing/Forwarding

VPN Routing/Forwarding (VRF) is an instance which is associated with a different virtual router, thus isolating each customer’s routing table from each other as well as from the provider’s (default) route table. A VPN instance consists of an IP routing table, a derived forwarding table, a set of interfaces that use the forwarding table, and a set of rules and routing protocols that determine what goes into the forwarding table.
