L3VPN Insights

What is L3VPN?

L3VPN (Layer 3 VPN) is a VPN that operates at the network layer (Layer 3) of the OSI model, typically using IP. It's commonly used by enterprises to connect multiple sites over a service provider's MPLS network. The service provider handles the routing and VPN management, providing a cost-effective and scalable solution compared to building their own private network. It allows secure and private communication between different locations by isolating traffic from other customers using the same network infrastructure.
