Usage restrictions
Updated at：2025-11-11
If a physical dedicated line is used for traffic interconnection, the following constraints must be satisfied:
- After completing the construction of the physical dedicated line and configuring the dedicated gateway, ensure bidirectional traffic flow by adding route entries in both route tables. The next hop in the local VPC route table should point to the corresponding dedicated gateway.
- A dedicated physical line channel can exclusively connect a single dedicated gateway within its respective VPC.
- The dedicated gateway and the physical line's local access point must be located in the same region.
- The CIDR blocks of the peer network used for a dedicated line and the local VPC must not overlap.
