ip vrf receive 这个参数其实用的很少,它和forwarding 最大的区别在于:如果你在一个三层接口上使用了forwarding,那么这个这个三层接口的IP 地址就被完全放进了你forwarding 的那个Vrf。而如果在三层接口上使用的参数是 receive,那么这个接口上的IP地址仍在还会在global的路由表里出现。
InIP-basedcomputer networks,virtual routing and forwarding(VRF) is a technology that allows multiple instances of arouting tableto co-exist within the same router at the same time. One or more logical or physical interfaces may have a VRF and these VRFs do not share routes therefore the pack...
VRF,全称为Virtual Routing and Forwarding,是一种在单一路由器上实现多个独立路由表的技术,每个VRF代表一个虚拟的路由器实例,用于隔离不同的网络或服务。每个VRF有自己的路由表,地址空间,接口集合,以及特定的路由协议,如MBGP,用于在PE设备之间分发路由信息。在MPLS VPN网络中,PE设备是关键组件,根...

vfs实现原理 vrf技术原理,VRFVRF(VirtualRoutingandForwarding,虚拟路由转发)技术通过在一台三层转发设备上创建多张路由表实现数据或业务的隔离,常用于MPLSVPN、防火墙等一些需要实现隔离的应用场景。网络需求某企业网络内有生产和管理两张网络,这两张网络独占接入和
现在PC1要发送一个数据包到2.2.2.2,R1从接口GE0/0/1收到了这个数据包,由于此时GE0/0/1已经绑定到了VRF1,因此在执行目的IP的路由查找的时候,查的是VRF1的路由表,查找到匹配的路由条目后,间个数据包从其指示的GE0/0/1口转发给下一跳192.168.100.2。

The VRF Full form in networking is Virtual Routing and Forwarding which is an IP based technology. Learn everything about VRF including its types, etc.
Virtual routing and forwarding (VRF) is a technology based on the operating principle of a physical router. Unlike a single router, virtual routers (VRs) can be run simultaneously as multiple instances. Each of these instances uses its own routing and forwarding table. Because each virtual ...
