Introduction to Open vSwitch (OVS)

ovs本质确实就是一个virtual switch，bridge和port概念，add-br就是添加一个桥，然后将port添加到桥上就能互通了。 记住几个关键概念show 查看br和port、add-br添加br、add-port 添加port到br、del-port 删除port从br、dump-ports 显示br下的ports。

With OVS installed and configured the next step will be installation of KVM packages on our Linux Server. Perform the operation by using the commands shared below.

This document provides detailed instructions for setting up and configuring Open vSwitch (OVS) bridges to work with the OVS-CNI plugin. Note that OVS-CNI does not automatically create or configure bridges; it's the administrator's responsibility t

Two connected bridges are not much different from a single bridge, so you might as well just have a single bridge with all your ports on it. If you still want to connect two bridges, you can use a pair of patch ports.

Open vSwitch (OVS) is a multilayer software switch. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols.

Linux VLAN Bridging Compatibility The ovs-vsctl program supports the model of a bridge implemented by Open vSwitch, in which a single bridge supports ports on multiple VLANs.
