VTI is a cisco proprietary protocol, but other vendors have similar route based vpn technology , which may or may not work between each other.

Hi Bogdan,

Thank you for fast response. Do you know what are similar protocols used by other vendors (juniper, huawei)?

I believe Juniper refers to it as route-based IPsec VPN.
