API Description

This API is used to create cross-region peering connections.
Domain name:
API name: CreateVpcPeeringConnectionEx

  • Cross-region peering connections are used to establish connectivity between VPCs in two different regions. The IP address ranges of both VPCs that need to be interconnected cannot overlap.
  • Cross-account peering connections take effect only when the receiver accepts the request. Peering connections between VPCs in the same account take effect immediately.
  • You can set a bandwidth for cross-region interconnection. For any changes made after the creation of the peering connection, contact customer service.
