ACI Application Centric Deployment (ACD) and Subnet Sharing with Route Leaking

Leave a Comment /

1. Overview In Cisco ACI, a powerful feature called route leaking enables applications and services to communicate seamlessly across Virtual Routing and Forwarding (VRF) instances. This allows for efficient data flow within the network infrastructure, even when applications reside in separate VRFs for security or isolation purposes. Route leaking achieves this by sharing routing information […]

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

VxLAN EVPN Fabrics External Connectivity – VRF Lite

Leave a Comment /

Overview VXLAN EVPN fabrics address the need for workload mobility, flexible resource allocation and multi-tenancy by decoupling workloads from the underlying physical infrastructure. This enables to treat workloads as portable units that can be easily moved across different compute resources within the data center. Workloads in the data center need the ability to connect to

Underlay Multicast Routing for VxLAN BUM Traffic

Leave a Comment /

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
