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。
intVLAN20ip vrf forwarding MYTESTVRF You need to take into account that addition of interface to VRF will remove all existing IP addresses configured on the interface. It is done in this way because it can help to avoid address duplication in the new routing table if some incautious engineer...
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...
VRF（Virtual Routing and Forwarding）是一种技术，可以将一个物理路由器分成多个逻辑路由器。每个逻辑路由器（也称为VRF实例）都可以配置自己的路由表和路由策略，以在逻辑上隔离另一个逻辑路由器。VRF 技术使得虚拟网络的构建变得更加容易，网络管理员可以在同一物理网络上提供多个独立的虚拟网络。这使得多...
Virtual Routing and Forwarding or VRF allows a router to run more that one routing table simultaneously. When running more routing tables in the same time, they are completely independent. For example, you could use overlapping IP addresses inside more VRFs on the same router and they will fun...
VRF配置Telnet或SSH访问,一、VRF介绍VRF(VirtualRoutingForwarding)虚拟路由转发表。VRF技术允许路由表的多个实例在同一路由器中同时存在。由于路由实例是独立的,因此可以使用重叠的相同或IP地址而不会相互冲突。VRF可以通过不同的路由表(称为转发信息库(FIB))在网络设
VRF全称是虚拟路由转发(Virtual Routing Forwarding)又称 VPN Instance(VPN 实例),是种虚拟化技术。在物理设备上创建多个VPN实例,每个VPN实例拥有独立的接口、路由表和路由协议进程等。简单理解是,将整个设备“分割”成多个小设备。每一个VPN实例就是相当于一个个独立的路由表,添加VPN实例相当于隔离建立多个独立的路由...

The layer 3 interfaces (VLAN interfaces, bonds, switch virtual interfaces/SVIs) associated with the VRF are enslaved to that VRF; IP rules direct FIB (forwarding information base) lookups to the routing table for the VRF device. The VRF device can have its own IP address, known as a ...
Virtual routing and forwarding (VRF) for asymmetrical virtual service provider (VSP) tunnelsIn one embodiment, a device in a network maintains first and second routing tables associated with a virtual private network (VPN) tunnel. The first and second routing tables comprise routing information used...
