Explanation

HA VPN over Cloud Interconnect requires two separate Cloud Router instances – one dedicated to the Interconnect VLAN attachments and a second one for the HA VPN tier. To finish your deployment, you must: 1. Create an HA VPN gateway and associate its two interfaces with your encrypted VLAN 2. Provision a new Cloud Router for the HA VPN tier (you cannot reuse the Interconnect-tier router). 3. Configure the peer VPN gateway resources and HA VPN tunnels against that new router. This separation ensures the Interconnect BGP session remains distinct from your HA VPN BGP session, as documented by Google’s HA VPN over Cloud Interconnect architecture.
