You are setting up a Google Cloud environment to connect to your on-premises network. Your configuration must access Cloud Storage APIs and Google Kubernetes Engine nodes over your private Cloud Interconnect. You have already configured a Cloud Router with Interconnect VLAN attachments. What steps should you take to configure the correct router advertisement settings on the Cloud Router?
You are setting up a Google Cloud environment to connect to your on-premises network. Your configuration must access Cloud Storage APIs and Google Kubernetes Engine nodes over your private Cloud Interconnect. You have already configured a Cloud Router with Interconnect VLAN attachments. What steps should you take to configure the correct router advertisement settings on the Cloud Router?
Explanation:
To enable connectivity to both Cloud Storage APIs and GKE nodes over a private Cloud Interconnect, the Cloud Router must advertise two types of routes: (1) the VPC subnets (for GKE nodes) and (2) the Google API VIP range 199.36.153.8/30 (for Cloud Storage APIs). The default route advertisement mode only advertises VPC subnets. Configuring a custom route advertisement allows adding the 199.36.153.8/30 prefix. However, to ensure VPC subnets (GKE nodes) are also advertised, the 'Advertise all visible subnets' option must be enabled in the custom configuration. This ensures both the VPC subnets and the custom API prefix are advertised to the on-premises network.
