  • Publication number: 20250015976
    Abstract: Techniques described herein provide procedures for reducing MACsec Key Agreement (MKA)-related traffic and improving resource allocation for MKA protocol through an EVPN environment. Techniques include leveraging Border Gateway Protocol (BGP) signaling for MKA between Provider Edge (PE) routers instead of between Customer Edge (CE) routers, which mitigates both hardware restrictions and scalability challenges with a new Xaas enablement. A new BGP-EVPN route type is defined that can communicate a set of MKA information along with an address destination associated with a provider edge device to establish a BGP MKA session and enable MACsec encryption/decryption at the provider edge device.
