Belete Ageze 2xCCIE | CCDE In a VXLAN EVPN fabric, L4-L7 connectivity play a vital role in securing and optimizing network traffic. L4-L7 services are typically connected to the leaf switches, often referred to as service leaf switches. The choice between a dual-attached and single-attached L4-L7 service node design for a VXLAN EVPN fabric depends […]

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

Designing ACI multi-site object names should not be an after thought since it has an implication during inter-site communication deployment. When contract with the right scope is applied between site-local EPGs the ACI objects are mirrored on the remote sites. The mirrored objects appear as if they are deployed in each of these sites’ controllers, while only actually being deployed in one of the sites. These mirrored objects are called “shadow” objects and they appear with the same names as the ones that were deployed directly to each site. Because of the shadow objects requirement for inter-site communication between site-local EPGs, this blogs focus on ACI multi-site object naming consideration an engineer need to be aware of.
