how to setup zerto test netwks with vLANs

Hi group, I would like to find feedback on how others have setup zerto sandbox networks for testing with vlans. I found this on the web – https://www.jpaul.me/2016/02/creating-a-zerto-failover-test-network. Have you used this approach, or something different?

Does anyone have lessons learned / suggestions on how they setup their failover network?

Thanks!
