You are setting up hybrid connectivity between your on-premises data center and Google Cloud using redundant Dedicated Interconnect connections. VLAN attachments are being deployed in us-central1 with an active/passive approach (interconnect-1 as active and interconnect-2 as backup). To enable BGP connectivity while adhering to Google's best practices, how should you configure the Cloud Router?
Explanation:
To implement an active/passive BGP setup with Google-recommended practices for Dedicated Interconnect, it's essential to configure the BGP sessions with the correct priorities and ASNs. The active connection should have a lower priority (e.g., 0) and the passive backup a higher priority (e.g., 200). Both VLAN attachments should use the same Google-side ASN for consistency, and the on-premises ASN should be distinct. Option B correctly follows these practices by setting the priorities as 0 and 200 for the active and passive connections respectively, using the same Google-side ASN (65100) for both, and a distinct on-premises ASN (65000).
