Are GCP HA VPN supported for connections to Cloud SWG services?

Products

• WSS add-on - All Traffic Pass-Through

Issue/Introduction

Google GCP offers a High-Availability VPN feature in GCP.

Is this feature usable to access Broadcom Cloud SWG systems instead of standard IPsec VPN configurations?

Environment

Cloud SWG with the IPsec tunnels coming from Google Cloud Compute.

Resolution

Google Cloud HA VPN option requires BGP configuration which Broadcom does not support [1].

However Broadcom does offer the ability to use GCP Express Connect which removes the need for IPsec tunnels and provides high-speed low latency from the customer environment to Broadcom GCP environment directly [2].
