The following SBC SWe in GCP deployment models are supported:
The High-Availability Front End (HFE) node is a public-facing node that allows sub-second switchover between Active and Standby SBC instances of an HA pair, as it negates the need for any IP reassignment. GCP requires each interface of a instance in a separate Virtual Private Network (VPC). Create a minimum of six VPCs for a full HFE set up (assuming all management interfaces for the SBC and the HFE node are in the same VPC). HFE 2.0 is an environment that uses a single HFE node with 5 interfaces. All trusted and untrusted traffic use the same node. Each interface's function is described in the following table: To use a HFE 2.0 environment, the startup-script for the SBCs requires the field HFE 2.1 has two HFE nodes, each responsible for a different type of traffic: Both HFE nodes require three interfaces, as follows: To use a HFE 2.1 environment, the startup-script for the SBCs requires the fields HFE Node Network Setup
