Virtual Route Forwarding or Virtual Private Network (VPN) Route Forwarding (VRF), is a mechanism that allows multiple instances of a routing table to exist on a router and work simultaneously. This mechanism allows for network paths to be segregated without using multiple devices, thereby increasing network security and eliminating the need for encryption and authentication. VRFs are generally used to create separate VPNs. Allowing Intrusion Prevention System (IPS) to be configured on a per-VRF basis means global parameters will be shared by multiple VPNs, providing VRF related information on the Security Device Event Exchange (SDEE) and syslog alerts.
