Virtual Private Cloud (VPC) provides the ClassicLink feature. This feature allows
classic network-connected Elastic Compute Service (ECS) instances to communicate with
cloud resources deployed in VPCs. Before you establish a ClassicLink connection, you
must enable the ClassicLink feature.
Background information
The ClassicLink feature allows classic network-connected ECS instances to communicate
with cloud resources such as ECS instances, ApsaraDB RDS instances, and Server Load
Balancer (SLB) instances that are deployed in VPCs. VPC-connected ECS instances can
access only ECS instances in a classic network that is already connected to the VPC.
VPC-connected ECS instances cannot access other cloud resources in the classic network
or ECS instances deployed outside the classic network. For more information, see Overview.
Procedure
- Log on to the VPC console.
- In the top navigation bar, select the region where the VPC is deployed.
- On the VPCs page, find the VPC that you want to manage and click its ID.
- In the upper-right corner of the VPC details page, click Enable ClassicLink.
- In the Enable ClassicLink dialog box, click OK.
After ClassicLink is enabled, the status of ClassicLink in the VPC Details section
changes to
Enabled.
