Supported VPN Configuration Types

DE.

NSX-T Data Center provides two types of VPN configurations: L3 VPN and L2 VPN.

L3 VPN: L3 VPN stands for Layer 3 Virtual Private Network. It is a type of VPN that uses IP protocol to create a secure tunnel between two endpoints. In NSX-T Data Center, L3 VPN can be configured using the IPSec VPN protocol. IPSec is an industry standard protocol that is widely used for secure communication over the internet. L3 VPN is commonly used for site-to-site connectivity, where two different networks are connected securely over the internet.

L2 VPN: L2 VPN stands for Layer 2 Virtual Private Network. It is a type of VPN that enables the extension of a Layer 2 network across a Layer 3 network. In NSX-T Data Center, L2 VPN can be configured using the L2 VPN protocol. L2 VPN is commonly used for connecting two data centers or extending a Layer 2 network between two remote sites.

Open VPN and SSL VPN+ are not supported VPN configuration types in NSX-T Data Center. Open VPN is an open-source VPN protocol that is widely used for creating secure point-to-point connections over the internet. SSL VPN+ is a proprietary VPN protocol developed by VMware that uses SSL/TLS for encryption and authentication. While these protocols can be used for VPN connections in other environments, they are not currently supported in NSX-T Data Center.

MPLS is also not a supported VPN configuration type in NSX-T Data Center. MPLS stands for Multi-Protocol Label Switching and is commonly used in service provider networks to provide VPN services to customers. However, NSX-T Data Center does not currently support MPLS-based VPN configurations.
