我已经安装了 Openstack，没有任何问题。我面临无法从其他网络访问控制器主机的问题。

在我的工作环境中，我在 Cisco 交换机上配置了许多 VLAN。

  • 用户 VLAN 为 (10.10.10.0/24.)
  • 服务器 VLAN 为 (192.168.100.0/24)。

控制器服务器 ext IP (192.168.100.100)，在控制器上创建网络/路由器后，用户 (10.10.10.0/24) 的网络无法 ping/访问 192.168.100.100，但在控制器的同一网络上 (192.168 .100.0/24) 仍然可以 ping 到控制器节点。

这意味着只有控制器的同一网络可以访问它，而其他网络不能。

那么如何使其可用于所有网络呢？

控制器的一些结果：

tcpdump：

verbose output suppressed, use -v or -vv for full protocol decode
listening on vxlan-1, link-type EN10MB (Ethernet), capture size 262144 bytes.
