无法访问提供商网络（Openstack Packstack Opendaylight集成）

[英]Cannot acces provider network (Openstack Packstack Opendaylight integration)

问题描述

我尝试使用OpenDayLight对使用packstack（Centos）构建的Openstack进行整数化。 这是我的拓扑 

Openstack Controller : 10.210.210.10 & 10.211.211.10
- eth1 : 10.211.211.10/24
- eth0 : 10.210.210.10/24

Openstack Compute : 10.210.210.20 & 10.211.211.20
- eth1 : 10.211.211.20/24
- eth0 : 10.210.210.20/24

OpenDayLight : 10.210.210.30
- eth1 : 10.210.210.30/24

Provider Network : 10.211.211.0/24
Tenant Network : 10.210.210.0/24

Openstack Version : Newton
OpenDayLight Version : Nitrogen SR1

这是我的packstack配置更改 

CONFIG_HEAT_INSTALL=y
CONFIG_NEUTRON_FWAAS=y
CONFIG_NEUTRON_VPNAAS=y
CONFIG_LBAAS_INSTALL=y

CONFIG_CINDER_INSTALL=n
CONFIG_SWIFT_INSTALL=n

CONFIG_NEUTRON_ML2_FLAT_NETWORKS=external
CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=external:br-ex
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth1
CONFIG_NEUTRON_OVS_BRIDGES_COMPUTE=br-ex

我尝试遵循此教程： http : //docs.opendaylight.org/en/stable-nitrogen/submodules/netvirt/docs/openstack-guide/openstack-with-netvirt.html

实例正在租户网络中获取dhcp并ping ip租户路由器网关。 但我无法ping通所有提供商网络。

与opendaylight集成时，这就是我的所有配置

我已经使用OpenStack和OpenDaylight成功部署了L3路由。

  1. 我在https://communities.cisco.com/community/developer/openstack/blog/2017/02/01/how-to-deploy-openstack-newton-with-opendaylight-boron-and-open上写了一个博客-vswitch 。
  2. 参考配置在https://github.com/vhosakot/Cisco-Live-Workshop/tree/master/openstack_ODL 。 请记住，新版本中的某些配置可能已更改。
  3. 使用https://github.com/openstack/networking-odl上的networking-odl项目，该项目可通过OpenDaylight自动安装OpenStack。
  4. 在https://github.com/openstack/networking-odl/blob/master/devstack/local.conf.example上还有另一个示例/示例配置文件。

您的意思是您无法ping 10.211.211.10吗？似乎是因为您已在br-ex上添加了eth1 ，所以您无法直接ping eth1，您可以尝试以下操作： 

ifconfig eth1 0
ifconfig br-ex 10.211.211.10

或者您可以从br-ex删除端口eth1 ： 

ovs-vsctl del-port br-ex eth1
