MPLS L3VPNs provide scalable, multi-tenant connectivity, but they lack native encryption. While IPsec is commonly used, MACsec (802.1AE) offers a high-performance alternative for securing MPLS L3VPN traffic at line rate (1G–100G+) without IPsec’s bottlenecks. Here’s the standard approach to deploying MACsec over MPLS L3VPN: 1. Understand Where MACsec Fits in MPLS L3VPN MPLS L3VPN operates at Layer 3, while MACsec works at Layer 2 (Ethernet). This… Continue reading Implementing MACsec over MPLS L3VPN: Best Practices and Standard Approach

MACsec: The Future of High Speed Ethernet Encryption for WAN Security
Introduction: The Need for Faster, More Secure Networks The explosion of cloud computing, IoT, and video streaming has pushed WAN bandwidth demands to unprecedented levels. While Ethernet speeds have evolved from 10G to 100G and beyond, encryption technologies have struggled to keep up. Enter MACsec (802.1AE)—a Layer 2 encryption standard that provides line-rate security without compromising performance. Unlike traditional IPsec, which operates at the IP… Continue reading MACsec: The Future of High Speed Ethernet Encryption for WAN Security
