You can create a connection between a virtual border router (VBR) and a virtual private cloud (VPC). This topic describes how to create and manage a VBR-to-VPC connection.

Prerequisites

A VPC and a VBR are created. For more information, see Create and manage a VPC and Create a VBR.

Create a VBR-to-VPC connection

  1. Log on to the Express Connect console.
  2. In the top navigation bar, select the region and choose VPC Peering Connections > VBR-to-VPC in the left-side navigation pane.
  3. On the VBR-to-VPC page, click Create Peering Connection.
  4. Perform the following operations to create a VBR-to-VPC connection:
    • Create a connection between a VBR and a VPC within the same account
      1. On the buy page, set the following parameters and click Buy Now.
        Parameter Description
        Billing Method

        Select a billing method for the peering connection. In this example, Subscription is selected.

        Account
        Specify whether to create a connection between a VBR and a VPC within the same Alibaba Cloud account or across different accounts.
        • Same-account: The VBR and VPC belong to the same Alibaba Cloud account. In this case, the system creates initiator and acceptor router interfaces, and automatically establishes the connection.
        • Cross-account: The VBR and VPC belong to different Alibaba Cloud accounts. In this case, you must create initiator and acceptor router interfaces, and initiate a connection request from the initiator.
        In this example, Same-account is selected.
        Connection Type

        Select the type of connection that you want to create. In this example, VBR-to-VPC is selected.

        Role

        Select the type of router interface that you want to create. By default, Create Initiator and Receiver is selected. In this case, the system automatically creates the initiator and acceptor router interfaces.

        Router type By default, VBR is selected. This specifies that the connection is initiated from the VBR.
        Region Select the region where the VBR is deployed.
        Access Point Select the access point to which the VBR is connected.
        Local VBR ID Select the ID of the VBR from the drop-down list.
        Peer Region Select the region where the VPC is deployed.
        Peer Router Type By default, VRouter is selected. This specifies that the connection is accepted by the VPC.
        Peer VPC ID Select the ID of the VPC from the drop-down list.
        Bandwidth Specify the maximum bandwidth.

        You do not need to specify the maximum bandwidth of the acceptor. The default bandwidth is used.

        Validity Select a subscription duration.

        You must select a subscription duration when you create a subscription peering connection. You can also select the Auto-renewal check box to enable auto-renewal.

      2. On the Confirm Order page, confirm the information, select Terms of Service, and then complete the payment.

        After the connection is established, the state of the initiator and acceptor changes to Activated.

    • Create a connection between a VBR and a VPC across different accounts
      1. On the buy page, set the parameters of the initiator and click Buy Now.
        The following table describes the parameters that are different from the ones when you create a connection for a VBR and a VPC within the same account. For more information about the other parameters, refer to the preceding section.
        Parameter Description
        Account

        Specify whether to create a connection between a VBR and a VPC within the same Alibaba Cloud account or across different accounts. In this example, Cross-account is selected.

        Role

        Select the type of router interface that you want to create. By default, InitiatingSide is selected. In this case, after you complete the payment, only the initiator router interface is created.

      2. On the Confirm Order page, confirm the information, select Terms of Service, and then complete the payment.

        After the initiator router interface is created, record the ID of the router interface.

      3. Use the Alibaba Cloud account for which you want to create the acceptor to perform the following operations: Log on to the Express Connect console.
      4. In the top navigation bar, select the region and choose VPC Peering Connections > VBR-to-VPC in the left-side navigation pane.
      5. On the VBR-to-VPC page, click Create Peering Connection.
      6. On the buy page, set the following parameters and click Buy Now.

        Select the type of connection that you want to create. In this example, VBR-to-VPC is selected.

        Role

        Select the type of router interface that you want to create. By default, AcceptingSide is selected.

        Router type By default, VRouter is selected. This specifies that the connection is accepted by the VPC.
        Region Select the region where the VPC is deployed.
        Local VPC ID Select the ID of the VPC.
        Peer Region Select the region where the VBR is deployed. The connection is initiated from the VBR.
