Evidence for Translation Approach
According to H3C, a PRC company in the industry :
“URPF（Unicast Reverse Path Forwarding，单播逆向路径转发）的主要功能是用于防止基于源地址欺骗的网络攻击行为。路由器接口一旦使能URPF功能，当该接口收到数据报文时，首先会对数据报文的源地址进行合法性检查，对于源地址合法性检查通过的报文，才会进一步查找去往目的地址的转发表项，进入报文转发流程；否则，将丢弃报文。”
According to Cisco, an American company in the industry:
” Network administrators can use Unicast Reverse Path Forwarding (Unicast RPF) to help limit the malicious traffic on an enterprise network. This security feature works by enabling a router to verify the reachability of the source address in packets being forwarded. This capability can limit the appearance of spoofed addresses on a network. If the source IP address is not valid, the packet is discarded. Unicast RPF works in one of three different modes: strict mode, loose mode, or VRF mode. Note that not all network devices support all three modes of operation. Unicast RPF in VRF mode will not be covered in this document.”
