How to create a High availability HA VPN gateway?

Answer 1

You can create a HA VPN gateway without the following resources and configure those resources later.

• VPN tunnels

• A peer VPN gateway resource

• BGP sessions

You must create these resources before your gateway can become operational.

Create an HA VPN gateway. When the gateway is created, two external IP addresses are automatically allocated, one for each gateway interface.

In the following commands, replace the options as noted below:

• Replace network with the name of your GCP network.

• Replace region with the GCP region where you need to create the gateway and tunnel.

• Replace gw-name with the name of the gateway.

gcloud compute vpn-gateways create gw-name \ --network network \ --region region

The gateway you create should look similar to the following example output. Note that a public IP address has been automatically assigned to each gateway interface:

 Created [https://www.googleapis.com/compute/v1/projects/project-id/regions/us-central1/vpnGateways/ha-vpn-gw-a].
 NAME        INTERFACE0    INTERFACE1   NETWORK   REGION
