DX Gateway

Creating a Global Direct Exchange Gateway

Scenarios

Before using Global Direct Exchange Gateway (DXGW) to implement various interconnection networking scenarios, you must create a DXGW instance first.

Before you begin

Complete VolcanoEngine account registration and real-name authentication.

Procedure

Parameter	Description	Example
Name	Set the name for the DXGW.	dxgw-01
Interconnection type	Select the interconnection type for the DXGW. Layer 2 interconnection: Used to build a direct dedicated network between on-premises data centers (IDCs). Traffic does not need to be relayed across regions. tip Layer 2 Interconnection is in the invite-only beta stage. To request a trial, please contact your account manager. Layer 3 interconnection: Allows IDCs to directly connect to cloud-based Virtual Private Cloud (VPC) resources in each region via the nearest access point. It supports various disaster recovery scenarios, including primary-backup redundancy and load redundancy. With the Site Interconnection feature enabled, routes can be propagated between sites through Virtual Interfaces, allowing IDCs to communicate with each other.	Layer 3 interconnection
ASN	Set the ASN (Autonomous System Number) for the DXGW. Configure it only when the interconnection type is Layer 3 interconnection. The valid range for DXGW ASN is: 137718, 64512 to 65534, and 4200000000 to 4294967294, where 137718 is the ASN of VolcanoEngine. Each DXGW ASN must be unique.	64512
Agreement	Follow the console guidance to review and accept the legal terms.	Check

What to do next

After the DXGW is created successfully, proceed with the following steps based on your business scenario:

Associate a Virtual Interface: Associate a Virtual Interface with DXGW to connect the Direct Connect (DC) Connection and DXGW.

(Optional) Enable site interconnection: For cross-region direct connectivity between IDCs, use the Site Interconnection feature of DXGW to interconnect traffic between IDCs in different regions.

Create an Ethernet Virtual Interface: Create an Ethernet VIF to connect the DC Connection and DXGW.

Associate a Virtual Interface: Associate the Ethernet VIF with DXGW so that the DXGW can establish an interconnection network over the DC Connection.

Create a bandwidth package: Create a bandwidth package for DXGW to enable cross-region traffic.
