Sharing Overview¶
What Is Sharing?¶
You can share an enterprise router in your account with other accounts.
You are the owner of the enterprise router.
Other accounts are the users of the enterprise router.
After you share your enterprise router with other accounts, these other users can attach their network instances to your enterprise router, so that their network instances can access your enterprise router.
You can share an enterprise router in your account with other accounts so that these other accounts can attach their VPCs to your enterprise router.
This example uses account A, account B, and account C to describe how you can build a network using one enterprise router. Table 1 describes the resources of each account.
If account A shares enterprise router (ER-A) with account B and account C, the VPCs of accounts B and C can be attached to ER-A. Figure 1 shows the networking.
Account | Enterprise Router | VPC |
|---|---|---|
A | ER-A | VPC-A-01 VPC-A-02 |
B | ER-B | VPC-B-01 |
C | ER-C | VPC-C-01 |

Sharing an Enterprise Router with Other Users¶
As the owner, you can share your enterprise router with other users. These other users can create attachments for your enterprise router.
If Auto Accept Shared Attachments is not enabled on your enterprise router, you must accept the attachment creation requests from other users.

Description
1
Owner
The owner creates a sharing to share an enterprise router with another user. This user can easily identify the shared enterprise router because its name is followed by Shared with me.
2
User
The user creates an attachment to the shared enterprise router. The attachment will be in the Pending acceptance state because Auto Accept Shared Attachments is disabled on the enterprise router.
3
Owner
The owner accepts the attachment request. The attachment status changes from Pending acceptance to Creating.
When the attachment status changes to Normal, the attachment is successfully created.
When the attachment status changes to Failed, the attachment fails to be created. Contact customer service.
After an attachment is created, you can perform Follow-up Procedure.
The owner can also reject the attachment request. If the owner rejects the request, the attachment status changes from Pending acceptance to Rejected, and the attachment fails to be created. If this happens, contact the owner.
If Auto Accept Shared Attachments is enabled on an enterprise router, the other users' requests to create attachments to this enterprise router will be automatically accepted without the approval from the owner.
