Your team is building an on-premises web application that needs direct RFC 1918 connectivity to GCP Compute Engine instances. Given these requirements:

✑ Your ISP is a Google Partner Interconnect provider.
✑ Your on-premises VPN device has 10 Gbps internet uplink/downlink capacity.
✑ A test VPN connection to GCP achieves only 500 Mbps max due to packet loss.
✑ Most traffic flows from GCP to on-premises.
✑ The application may burst to 1.5 Gbps during peak Interconnect transfers.
✑ The solution should minimize cost and complexity.

What connectivity solution should you implement?
