We are planning to extend management to an additional data center through Layer 2, but does not want to add additional NSX-T licensing, What will be the better option
Deploy a standalone Edge as the IPSec VPN. OR Deploy a standalone Edge as the L2 VPN client.
Please help me with better option.
If you need Layer-3 connectivity only then you can do IPSec VPN.
IPSec VPN can also do secure connections between Edge and non-NSX components (e.g. physical router/firewall)
But if you need Layer-2 connectivity of the networks behind Edge to be extended to the other DC on same Layer-2 network then it will be L2VPN
