neutron网络部署
按照官方文档做的Installation Guide for Ubuntu 14.04 (LTS)
1.为什么ping不通203.0.113.101
2.这上面的203.0.113.101是哪个网卡或者路由器的地址吗，到底是谁的地址，如果换成别的该怎么换？
3.这两条命令是意思我是这样理解的
ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex INTERFACE_NAME（实际用的是eth0）
先创建了一个网桥，再把eth0插到这个网桥上面，相当于真实环境里面用网线连接把电脑和网桥，4.openstack网络和真实环境是如何对应的，比如我的：
---------------------------------------------------------------------
节点 + 网卡 + ip
--------------------------------------------------------------------
controller + em1 + 192.168.1.30
--------------------------------------------------------------------
network + em1 + 192.168.1.131
network + em1：0 + 10.0.1.121
network + eth0 + iface eth0 inet manual
--------------------------------------------------------------------
network + em1 + 192.168.1.132
network + em1：0 + 10.0.1.132
--------------------------------------------------------------------

能不能具体到哪一步啊，我看好多地方有防火墙和网络模式方向的配置。控制节点：
1./etc/neutron/plugins/ml2/ml2_conf.ini
[ml2]
type_drivers = flat,gre
tenant_network_types = gre
mechanism_drivers = openvswitch
[ml2_type_gre]
tunnel_id_ranges = 1:1000
[securitygroup]
enable_security_group = True
enable_ipset = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
2./etc/nova/nova.conf
network_api_class = nova.network.neutronv2.api.API
security_group_api = neutron
linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver
firewall_driver = nova.virt.firewall.NoopFirewallDriver
网络节点：
/etc/neutron/plugins/ml2/ml2_conf.ini
[ml2]
type_drivers = flat,gre
tenant_network_types = gre
mechanism_drivers = openvswitch
[ml2_type_flat]
flat_networks = external
[ ml2_type_gre]
tunnel_id_ranges = 1:1000

enable_security_group = True
enable_ipset = True

[agent]
tunnel_types = gre
3./etc/neutron/dhcp_agent.ini
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
use_namespaces = True
dhcp_delete_namespaces = True

1、使用的什么网络模式，vlan gre vxlan
2、是否有防火墙，noopfirewall驱动可以设置无防火墙模式
3、路由是否正确、dntp sntp是否正确
4、物理链路是否通，手动设置ovs flow收起
