== Unicast RPF ==
'''Unicast RPF''' (uRPF), as defined in RFC 3704, is an evolution of the concept that traffic from known invalid networks should not be accepted on interfaces from which theyit should never have originated. The original idea as seen in RFC 2827 was to block traffic on an interface if it is sourced from forged IP addresses. It is a reasonable assumption for many organizations to simply disallow propagation of private addresses on their networks unless they are explicitly in use. This is a great benefit to the Internet backbone as blocking packets from obviously bogus source addresses helps to cut down on IP address spoofing which is commonly used in [[denial of service|DoS]], [[distributed denial of service|DDoS]], and network scanning to obfuscate the source of the scan.<ref>{{cite web
