Overview Route leaking in Cisco VXLAN EVPN fabrics plays a critical role in enabling communication between workloads residing in different L3 VXLAN Network Segments (VNIs), VRFs. It essentially allows these workloads to seamlessly access resources and services provided by shared services or external networks. VRF (Virtual Routing and Forwarding) – VRFs are leveraged to establish

Belete Ageze – 2xCCIE | CCDE Overview While Cisco VxLAN leverages BGP EVPN for the control plane, it requires mechanisms to manage Broadcast, Unknown Unicast, and Multicast (BUM) traffic within the VxLAN fabric. VxLAN fabrics typically rely on multicast replication in the underlay network to efficiently forward BUM traffic. Although ingress replication serves as an

VxLAN EVPN Multi-site architecture is one of the widely deployed DC network solutions that can be scaled to thousands of switches across a wide range of geographical regions. VxLAN and MPBGP creates a powerful technology used to build a large, secure, and resilient multi-tenant web scale fabric that can scale to host hundreds of thousands of systems. In this document, VxLAN EVPN Multisite with two sites (SITE1 and SITE2) and inter-site network (ISN) will be configured for seamlessly extending layer 2 and layer 3 using anycast BGWs. All configurations necessary for full operation will be included…
