L3VPNs Insights

What is L3VPNs?

Layer 3 VPNs (L3VPNs) are a type of VPN built on top of an IP network using technologies like MPLS (Multiprotocol Label Switching). They enable service providers to offer private, secure, and reliable connectivity between geographically dispersed sites for their customers. The service provider manages the routing between the customer sites (VPN endpoints), hence "Layer 3." Common use cases include connecting branch offices, data centers, and cloud environments, providing businesses with a cost-effective alternative to dedicated private lines.
