To connect a transit router of Account B to a network instance of Account A, such as virtual private clouds (VPCs), virtual border routers (VBRs), Cloud Connect Network (CCN) instances, Express Connect Routers (ECRs), and IPsec-VPN connections, you must use Account A to grant permissions to the transit router of Account B. This topic describes how to grant a transit router permissions on network instances that belong to another Alibaba Cloud account.
Billing
After you connect a VPC, VBR, ECR, or IPsec-VPN connection to an Enterprise Edition transit router, you are charged a connection fee and a data forwarding fee. When you grant a transit router permissions on a network instance, you can specify an Alibaba Cloud account to pay the fees. You can specify the Alibaba Cloud account to which the network instance belongs or the Alibaba Cloud account to which the transit router belongs as the payment account. For more information about the billing of Enterprise Edition transit routers, see Billing rules.
Limits
A transit router that is created by an Alibaba Cloud account on the China site can connect only to network instances that are created by Alibaba Cloud accounts on the China site. A transit router that is created by an Alibaba Cloud account on the International site can connect only to network instances that are created by Alibaba Cloud accounts on the International site.
You cannot change the payment account within 1 hour after you connect an Enterprise Edition transit router to a network instance that belongs to a different Alibaba Cloud account. If you want to change the payment account again, the time period from the last change of payment account must be at least 1 hour.
For example, you connect an Enterprise Edition transit router of Account B to a VPC of Account A at 09:00:00 (UTC+8) on December 24, 2021. You specify Account A to pay the connection fee and data forwarding fee. In this case, you cannot change the payment account to Account B until 10:00:00 (UTC+8) on December 24, 2021.
You cannot directly change the payment account after you connect an Enterprises Edition transit router to a network instance that belongs to a different Alibaba Cloud account. You must close the connection between the Enterprises Edition transit router and the network instance before you can change the payment account. For more information, see Change the payment account.
Prerequisites
Before you grant a transit router permissions on a network instance, make sure that the following requirements are met:
The account to which the network instance belongs and the account to which the transit router belongs are of the same type.
A transit router that is created by an Alibaba Cloud account on the China site can connect only to network instances that are created by Alibaba Cloud accounts on the China site. A transit router that is created by an Alibaba Cloud account on the International site can connect only to network instances that are created by Alibaba Cloud accounts on the International site.
The ID of the Alibaba Cloud account to which the transit router belongs is obtained.
The ID of the Cloud Enterprise Network (CEN) instance to which the transit router belongs is obtained.
If you want to grant a transit router permissions on a VBR, you are authorized to manage VBR permissions. For more information, see Attach a VBR to a CEN instance that belongs to a different account.
If you want to grant a transit router permissions on an IPsec-VPN connection, the IPsec-VPN connection is not associated with a resource.
If the IPsec-VPN connection is associated with a VPN gateway, you cannot associate the IPsec-VPN connection with a transit router of the same or a different Alibaba Cloud account.
If the IPsec-VPN connection is associated with a transit router, you must first disassociate the IPsec-VPN connection from the transit router. For more information, see Delete a network instance connection.
