You can establish a peering connection between two VPCs or between a VPC and a VBR.
Initiator and acceptor
When you establish a peering connection, one end (VPC or VBR) of the connection is the initiator, and the other end is the acceptor. Only the initiator can initiate a connection. The acceptor can only wait for the initiator to initiate a connection. The initiator and the acceptor are only used to control the process of connection establishment. After the connection is established, the communication link is bidirectional and there is no difference between the initiator and the acceptor.
For interconnections between VPCs under the same account, Express Connect provides an option to create the initiator and the acceptor at the same time. You do not need to manually initiate the connection. The system will automatically initiate and establish the connection. For interconnections between VPCs under different accounts, you must manually initiate a connection.

---|---|---|
Is this end charged when VPCs are interconnected in the same region? | No | No |
Is this end charged when VPCs are interconnected between different regions? | Yes | No |

Connection process and status
In the peering connection process, the initiator initiates a connection. The acceptor then receives the connection, after which the connection is established successfully.
