Dear gods of openstack development:

 HUAWEI CLOUD's large second-tier network can be combined with migration tools to make automated migration tools, disaster recovery tools, 

 etc. Huawei's second-tier tools: https://support.huaweicloud.com/intl/en-us/usermanual-vpc/vpc_l2cg_0001.html

In addition, the Linux kernel supports vxlan. 

I hope that it can be integrated into a similar Huawei l2cg network tool in the future to achieve a single host dynamic migration with the same intranet IP address.

Vigorously promote mutual assistance migration between clouds and their disaster recovery solutions.

By using the cloud host linux kernel vxlan technology, the cost can be reduced by making large-scale Layer 2 network connection.

Customers can even make a large intranet in the world, for example, multiple data centers around the world make a large 10-segment network.
