给实例绑定浮动ip的时候提示以下错误：
错误：External network 6809a712-4e4e-407a-b651-88d3034a3929 is not reachable from subnet cc16ed3e-54d2-4e42-a61f-740f2c5229fb. Therefore, cannot associate Port 0add2268-31b6-44bf-b136-215d4fbaca44 with a Floating IP.Neutron server returns request_ids: ['req-a7cd9d7f-77f9-4d37-8dc9-a7166074c7da']
看了日志有以下错误：
