Security features in MPLS L3VPN
- [Instructor] Welcome back to the Designing MPLS L3VPN section of the MPLS L3VPN Foundation and Implementation course. This is the fourth video, Security Features in MPLS L3VPN. By the end, you will explore how MPLS L3VPN ensure secure data transmission. Let's lock it down. L3 VPNs carry sensitive customer data over a shared MPLS network, so security is critical. The good news? MPLS L3VPN has built-in features to keep data private and safe without needing extra encryption. Let's see how it works. First up, traffic isolation. Each customer's data stays in its own virtual routing table, a VRF, and provider edge routers. VPN A's traffic can't leak into VPN B's, even if they share the same network. This separation is hardwired into the design. Labels and VRFs act like walls, keeping data apart. Next, label-based forwarding. In the MPLS core, packets travel with labels, not IP headers exposed. Core routers only see the outer label and switch sheet, never picking at the customer's IP data.…
