openstack网络场景描述

This scenario describes a legacy (basic) implementation of the OpenStack Networking service using the ML2 plug-in with Open vSwitch. The example configuration creates one flat external network and one VXLAN project (tenant) network. However, this configuration also supports VLAN external networks, VLAN project networks, and GRE proj ect networks. To improve understanding of network traffic flow, the network and compute nodes contain a separate network interface for VLAN project networks. In production environments, VLAN project networks can use any Open vSwitch bridge with access to a network interface. For example, the br-tun bridge ect networks.
