Unicast Reverse Path Forwarding (URPF) is a function that checks the validity of the source address of IP packets received on an interface. This in an attempt to prevent Denial of Service attacks based on IP address spoofing.

URPF checks validity of a source address by determining whether the packet would be successfully routed as a destination address. Based on configuration, the check made can be for existence of any route for the address, or more strictly for a route out the interface on which the packet was received by the device. When a violating packet is detected, it can be dropped. This MIB allows detection of spoofingevents.
