Question

Your company has provisioned a single 10-Gbps Dedicated Interconnect connection at a Google colocation facility. Traffic to Google Cloud has grown, and the network team wants to increase capacity to 20 Gbps on the same connection while keeping a single logical link between your on-premises router and Google's edge. What is the correct way to achieve this?

Accepted Answer

Add a second 10-Gbps circuit to the existing Dedicated Interconnect connection so both links form a single LACP bundle terminating on the same Google edge device.

Answer

Order a second 10-Gbps Dedicated Interconnect connection; Google automatically adds it to the same link bundle and load-balances traffic across both.

Answer

Create a second VLAN attachment on the existing 10-Gbps connection; each attachment provides an additional 10 Gbps of capacity.

Answer

Upgrade the VLAN attachment capacity setting from 10 Gbps to 20 Gbps in the Cloud Console; Google reprovisions the port speed dynamically.
