==Comparision to Reverse-path Filtering==
Reverse Path Filters are typically used to disable asymmetric routing where an IP application has a different incoming and outgoing routing path. Reverse path filtering is a Linux Kernel feature. So major functionality is to prevent packet entering from one interface leaving via the other interfaces. Reverse-path Filtering is a feature of the [[Linux Kernel]],<ref name="professional Linux-1"/> but Reverse-path forwarding(RPF) is the protocol of the IP [[multicast]] routing. <ref name="professional Linux-1"> professional Linux- 1 May 2018:[https://www.theurbanpenguin.com/rp_filter-and-lpic-3-linux-security/ rp_filter and LPIC-3 Linux Security | professional Linux software development'']</ref> <ref name="Cisco unicast-reverse-path-forwarding-1"> CISCO Security Research & Operations- 3 June 2015:[https://www.cisco.com/c/en/us/about/security-center/unicast-reverse-path-forwarding.html Understanding Unicast Reverse Path Forwarding | Cisco -unicast-reverse-path-forwarding '']</ref>
