VETH打通不同VRF的基础配置|This allows e.g. older ping implementations to be run with specifying the device but without executing it in the VRF. This option can be disabled so that packets received in a VRF context are only handled by a raw socket bound to the VRF, and packets in the default VRF are only handled by a socket not bound to any VRF: Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The goal of this mechanism is to ensure zero packet loss in the presence of network congestion. The first flow control mechanism, the pause frame, was defined by the IEEE 802.3x standard.|Programmable Internetworking & Communication Operating System Docs ...Click Spaces -> Space Directory to see docs for all releases ...|set ip vrf VRF1 next-hop 192.168.1.1. when we enter the command < ip vrf receive VRF1 > it adds the connected subnet of the global interface to the vrf routing table and traffic from global to vrf is policy routed by the route-map applied under the under.

Thanks for this post, its quite helpful. A couple of questions though: - how do I express the desire to attach a libvirt VM to the inner bridge (vibr0 in your examples)?If management VRF is enabled, and you want to find the next-hop route in management VRF when running the commands traceroute/SCP/ping/apt get/SSH at Linux prompt, that is, using Eth0/1 management interface as the route interface, you have to add ip vrf exec mgmt-vrf before the commands.. The example format of these commands is shown below:|这说明电脑连接路由器是通的,网络效果好。. 下面按住键盘的Ctrl+c终止它继续ping下去,就会停止了,会总结出运行的数据包有多少,通断的有多少了。. 3. ping-a的使用.
