User guide for Alibaba Cloud Virtual Private Cloud (VPC) covering network setup, components, and management.
The guide introduces Alibaba Cloud's Virtual Private Cloud (VPC), a customizable isolated network environment that lets users control IP ranges, subnets, routing tables, and gateways. It explains the differences between classic and dedicated networks and lists the regions where VPC is available.
It details how to create and manage VPC resources such as VSwitches, routers (VRouter), route tables, and security groups, including constraints (e.g., one router per VPC) and operational steps. The document also provides usage scenarios, technical principles, and best‑practice recommendations for connecting on‑premises data centers via VPN or dedicated lines. This manual is written in Chinese.
| Router count per VPC | 1 |
|---|---|
| Switch type | 3‑layer switch, no 2‑layer broadcast or multicast |
| Route table count per router | 1 |
| Supported routing protocols | Static routing only; BGP and OSPF not supported |
| CIDR block editability | Cannot be modified after VPC creation |
Each VPC has exactly one router.
No, the CIDR block cannot be modified once the VPC is created.
All cloud resources inside the VPC, such as security groups, switches, instances, and route entries, must be deleted first.
