You can create a peering connection between a virtual border router (VBR) and a virtual private cloud (VPC) to enable communication between private networks.
Initiator and acceptor
A VBR-to-VPC connection is established by using an initiator and an acceptor. Only the initiator can initiate the peering connection. The acceptor must wait for the initiator to initiate the peering connection. The initiator and acceptor are only used to control how a peering connection is established. Data transmission between the initiator and acceptor is bidirectional. Therefore, after a peering connection is established, both the initiator and acceptor can send and receive data.
For a VBR-to-VPC connection, the system automatically creates the initiator and acceptor and sends connection requests from the initiator to the acceptor to establish the connection. You do not need to manually configure the initiator to send connection requests.

|Initiate the connection||Supported||Not supported|
|Send messages to the peer after the connection is established||Supported||Supported|
The initiator of a peering connection sends a request to the acceptor. After the acceptor accepts the request, the connection is established.

Renewal is supported.
You are charged only for the initiator of a VBR-to-VPC connection. You are not charged for the acceptor. The fees vary based on the maximum bandwidth of the initiator and region.
- You are not charged if the initiator and acceptor are deployed in the same region.
