Create VPC peer-to-peer connection

Disaster recovery VPC connected via peering with multiple business VPC

In Huawei Cloud Disaster Recovery, the disaster recovery host needs to be restored to the planned production business VPC. Therefore, it is necessary to configure cross VPC peer-to-peer connections in Huawei Cloud, configure the disaster recovery VPC with the business VPC, and add peer-to-peer connection routing. Mainly used for disaster recovery, the disaster recovery VPC where HyperBDR is located can access the business VPC through the intranet to recover virtual machines for data recovery.
