Reverse-path forwarding (RPF) is a technique used in modern routers for the purposes of ensuring loop-free forwarding of multicast packets in multicast routing and to help prevent IP address spoofing in unicast routing. In standard unicast IP routing, the router forwards the packet away from the source to make progress along the distribution tree and prevent routing loops. In contrast, the router's multicast … Webdelete ip rpf-route-static [vpn-instance vpn-instance-name] 可以通过 undo ip rpf-route-static 命令删除指定的组播静态路由外,也可以通过 delete ip rpf-route-static 命令删除所有的组播静态路由。 1.7 配置按照最长匹配选择RPF路由 1. 功能简介

WebUnicast RPF wird für die IPv4- und IPv6-Protokollfamilien sowie für die VPN-Adressfamilie (Virtual Private Network) unterstützt. Unicast-RPF wird auf Schnittstellen, die als Tunnelquellen konfiguriert sind, nicht unterstützt. Dies betrifft nur die Transitpakete, die den Tunnel verlassen. WebA unicast reverse-path-forwarding (RPF) check is a tool to reduce forwarding of IP packets that might be spoofing an address. A unicast RPF check performs a forwarding table lookup on an IP packet’s source address, and checks the incoming interface. The router or switch determines whether the packet is arriving from a path that the sender diani to wasini island
