Implementing MACsec over MPLS L3VPN: Best Practices and Standard Approach
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
