openstack 下网络[路由绑定]故障解决

1. 查询网络信息

[root@kf-test-pinyun-048228 ~(keystone_admin)]# neutron net-list | grep w2 | 01a7ab13-65a8-4300-a53b-d6a774414c2a | w2 | 67f3da0b-a513-4857-8ad7-2283494a3b4f 192.168.0.0/24 |

2. 查询子网信息

[root@kf-test-pinyun-048228 ~(keystone_admin)]# neutron subnet-list | grep 67f3da0b-a513-4857-8ad7-2283494a3b4f | 67f3da0b-a513-4857-8ad7-2283494a3b4f | 2 | 192.168.0.0/24 | {"start": "192.168.0.21", "end": "192.168.0.200"} |

3. 查询当前路由信息

[root@kf-test-pinyun-048228 ~(keystone_admin)]#neutron router-list | grep ly2 | 698a3113-e94d-4c5a-ba62-870c9c7897bc | ly2 | {"network_id": "c3d7ba94-4360-4f3f-a9c8-83cda089dfa7", "enable_snat": true} |

4. 添加网络接口

[root@kf-test-pinyun-048228 ~(keystone_admin)]#neutron router-list | grep ly2 | 698a3113-e94d-4c5a-ba62-870c9c7897bc | ly2 | {"network_id": "c3d7ba94-4360-4f3f-a9c8-83cda089dfa7", "enable_snat": true} | [root@kf-test-pinyun-048228 ~(keystone_admin)]#neutron router-interface-add 698a3113-e94d-4c5a-ba62-870c9c7897bc 67f3da0b-a513-4857-8ad7-2283494a3b4f 400-{u'NeutronError': {u'message': u'Bad router request: Subnet for router interface must have a gateway IP', u'type': u'BadRequest', u'detail': u''}}

检查原因

重新创建一个子网
