Openstack-Neutron
Openstack 無法從其他網路訪問控制器節點
我已經安裝了 Openstack,沒有任何問題。我面臨無法從其他網路訪問控制器主機的問題。
在我的工作環境中,我在 Cisco 交換機上配置了許多 VLAN。
- 使用者 VLAN 為 (10.10.10.0/24.)
- 伺服器 VLAN 為 (192.168.100.0/24)。
控制器伺服器 ext IP (192.168.100.100),在控制器上創建網路/路由器後,使用者 (10.10.10.0/24) 的網路無法 ping/訪問 192.168.100.100,但在控制器的同一網路上 (192.168 .100.0/24) 仍然可以 ping 到控制器節點。
這意味著只有控制器的同一網路可以訪問它,而其他網路不能。
那麼如何使其可用於所有網路呢?
控制器的一些結果:
tcpdump:
verbose output suppressed, use -v or -vv for full protocol decode listening on vxlan-1, link-type EN10MB (Ethernet), capture size 262144 bytes.

由於預設路由是內部介面,因此使用者無法訪問 Openstack。執行以下命令後,問題解決。
ip route del 預設通過 10.0.0.1
