When you create a Dedicated Interconnect connection, you must take the following steps to successfully create and configure an interconnect:
- 1. Order a Dedicated Interconnect
- Submit an order, specifying the details of your interconnect. Google emails you an order confirmation. After your resources have been allocated, you'll get another email with your LOA-CFAs.
- 2. Send LOA-CFAs
- Send the LOA-CFAs to your vendor. They will provision the cross connects between the Google peering edge and your on-premises network. Google automatically starts testing the light levels on each allocated port after 24 hours.
- 3. Test the interconnect
- Google sends you automated emails with configuration information for two different tests. First, Google sends an IP configuration to test light levels on every circuit in an interconnect. After those tests pass, Google sends the final IP configuration to test the IP connectivity of each interconnect's production configuration.
- Apply these configurations to your routers so that Google can confirm connectivity. If you don't apply these configurations (or apply them incorrectly), Google sends an automated email with troubleshooting information. After all tests have passed, your interconnect is ready to use.
- 4. Create VLAN attachments and establish BGP sessions
- When your interconnect is ready to use, you need to connect VPC networks to your on-premises network. To do that, create a VLAN attachment, specifying an existing Cloud Router that's in the VPC network that you want to reach. Using the information from the attachment, establish a BGP session between the Cloud Router and your on-premises router to start sending traffic between networks.
