# Cloud VPN Dynamic Module
## Example
This module makes it easy to deploy a [Classic VPN](https://docs.cloud.google.com/network-connectivity/docs/vpn/concepts/overview#classic-vpn) with dynamic (BGP) routing.
This example shows how to configure a single VPN tunnel using a couple of extra features

## Examples
### Classic VPN with single tunnel
This example shows how to configure a single VPN tunnel using a couple of extra features:
- custom advertisement on the tunnel's BGP session; if custom advertisement is not needed, simply set the `custom_advertise` attribute to `null`
- internally generated shared secret, which can be fetched from the module's `random_secret` output for reuse; a predefined secret can be used instead by assigning it to the `shared_secret` attribute
