I need help Setting up AWS Direct Connect Between two DCs in Melbourne

To set up AWS Direct Connect between your on-premises data center in Melbourne and AWS, here's what you need to know:

Getting Started: First, you'll need to work with an AWS Direct Connect Partner in the Melbourne location to establish the physical network circuits and colocation space. You can request a dedicated connection through the AWS Direct Connect console.

Connection Setup Process:

1. Sign into the Direct Connect console and create a connection
2. Select the Melbourne Direct Connect location
3. Choose your port speed (available options are 1 Gbps, 10 Gbps, 100 Gbps, or 400 Gbps)
4. Select whether you're connecting through a Direct Connect partner
5. Specify your service provider from the list, or select "Other" if your provider isn't listed

After Requesting: Once you submit your connection request, AWS will issue a Letter of Authorization and Connecting Facility Assignment (LOA-CFA). You'll need to provide this document to your network provider to order a cross connect. The LOA-CFA is digitally signed and watermarked for authentication.

Creating Virtual Interfaces: After the physical connection is established, you'll need to create virtual interfaces (VIFs) to actually route traffic. For connecting to VPCs, you can create either:

• Private virtual interfaces for direct VPC connectivity
• Transit virtual interfaces if you're using Transit Gateway (recommended for standard use cases with multiple VPCs)

Important Considerations:

• Port speed cannot be changed after submission, so choose carefully
• Connections must be activated within 90 days or they'll be deleted
• For production environments, it's highly recommended to configure redundant connections for failover purposes
• You'll need to download and configure router settings once your virtual interface is created

The Direct Connect service provides more reliable, consistent network performance compared to internet-based VPN connections, with the added benefits of potentially lower costs and higher bandwidth for your production traffic.
