This NetBrain Learning Path is a guided, hands-on journey that teaches network teams how to use NetBrain to build an always-current network digital twin, automate troubleshooting, standardize configuration and compliance through assessments with features such as intents, runbooks, scheduling, and dashboards.

This learning path introduces you to deploying and operating data center fabrics using Arista CloudVision Portal as your centralized orchestration and automation platform. You'll onboard Arista switches into CloudVision, reconcile their configuration with configlets, and build a VXLAN EVPN fabric using MLAG, VRFs, and Layer 2/Layer 3 networks for tenant segmentation. You'll then configure inter-VRF route leaking, and conclude by integrating multiple fabrics in a scalable, multi-domain architecture, all while leveraging CloudVision for centralized visibility and streamlined operations.

VMware NSX Datacenter(NSX-T) platform allows the creation of secure virtual networks on top of your current physical network and virtual server infrastructure. SDN abstracts the underlying infrastructure of your network and programs separate virtual networks using the software. Using the NSX-T manager to create the NSX infrastructure, we prepare the Compute and Edge hosts participating in NSX. The compute hosts connect to the DC fabric, typically a CLOS or Spine/Leaf architecture. The Edge is connected to the DC fabric and external switches to provide public and private routing to WAN and Internet. Using the software, NSX can recreate entire physical networks, from the layer two switching, complex BGP routing, and FWs load balancers VPNs. This is possible by creating layer 3 Virtual Tunnel Endpoints (VTEPs) that use the Geneve encapsulation protocol to create an overlay in the compute and Edge cluster hosts. This overlay can then build layers two and three segments to connect our Virtual NSX routing and switch infrastructure. This Geneve Encapsulated Overlay also allows us to create a Physical to Virtual (P/V) point where we can either encapsulate the virtual networks and send them across the layer three underlays or decapsulate to connect to devices outside NSX.

There are several universal architectures in the Arista design portfolio. The Enterprise Universal Cloud Network can be used in the data center and in the Cognitive Campus, and the Enterprise Anycloud Network expands beyond the data center. All of these designs deliver the Arista Unified AnyCloud Architecture offering unified orchestration, management and telemetry with CloudVision. Arista's guiding principles are Universal(Common architectures from small to huge), Simple(a single operating system for all platforms and hardware), Open(standards-based features and functions), Programable(Easy to use APIs and automation), and Visible(Full state Telemetry and flow information) The key to these guiding design principles is the use of the Arista EOS architecture for its hardware and software-based devices. EOS is based on a Linux kernel, standard and fully open. EOS uses agent processes, that use a Publish/Subscribe model to populate the NetDB on each device which contains all device states. NetDB can then be used by Aristas CloudVision products to offer full-state telemetry and flow information for the entire Universal Architecture. Because Arista is using a single binary for all hardware and software-based devices Arista can implement hardware abstraction. Unlike some other manufacturers, Arista uses the latest Merchant Silicon and when coupled with the standard open EOS kernel allows very fast development cycles, fewer bugs, and faster adoption by customers since it is the same EOS.

This learning path will walk through many different types of physical media from coaxial cable to fiber. It will also contain a brief history of Ethernet and the OSI Model.

This learning path on foundational Border Gateway Protocol (BGP) provides a comprehensive introduction and deep dive into the core aspects of BGP, the backbone of the internet's routing architecture. It starts by explaining the basics of BGP, including its purpose, operation, and fundamental concepts such as Autonomous Systems (AS), BGP sessions, and the BGP routing table. The series progresses to cover more advanced topics, such as BGP path selection, route advertisement, and the implementation of various BGP attributes like Local Preference, AS Path, and MED. Through practical examples, configurations, and troubleshooting scenarios, viewers gain a thorough understanding of how BGP facilitates global data exchange and the techniques network engineers use to optimize and secure BGP networks. The series aims to equip network professionals with the knowledge needed to manage and optimize BGP in real-world environments, emphasizing best practices and common pitfalls.

The Cisco ACI: Tenant & Fabric Connectivity learning path is the second part of our ACI fundamentals training, following the "Cisco ACI Fabric Initialization and Hypervisor Connectivity" path. This path covers two key areas: 1) Fabric Infrastructure configurations, which involve physical fabric setup, including vPCs, VLANs, loop prevention, underlay BGP protocol, etc. 2) Tenant Configurations, defining logical constructs like application profiles, bridge domains, and EPGs. In this Learning Path, students will learn to create Tenants, Application Profiles, Bridge domains, and EPGs, by using objects for connectivity within a physical ACI fabric. They will also discover how to connect Layers 2 and 3 to external networks and explore methods for segmentation using contracts and filters to support both Inter-EPG and Intra-EPG segmentation.

This learning path on foundational Open Shortest Path First (OSPF) provides a comprehensive introduction and deep dive into the core aspects of OSPF. It starts by explaining the basics of OSPF, including its purpose, operation, and fundamental concepts such as OSPF Neighbors, advertising routes, authentication, OSPF network types, and many others. This learning path aims to equip network professionals with the knowledge needed to manage and optimize OSPF in real-world environments, emphasizing best practices and common pitfalls.

This is part 1 of our ACI fundamentals training, with Part 2, "Cisco ACI: Tenant & Fabric Connectivity," as the next step in the series. Cisco's APIC functions like a switch supervisor, configuring the fabric as if it were a single switch. The Spine/Leaf fabric discovery and self-assembly occur seamlessly, similar to plugging in the supervisor (APIC), fabric module (Spine), and blades(Leafs). This Learning Path delves into ACI's discovery process, fabric construction, and its extension to hypervisors via VMM integration, thereby expanding ACI control to the hypervisors' vSwitch. Part 2 will dive deeper into configurations that are applied to designate ports as access, trunk, or L3 ports.

This learning path builds a practical understanding of IPv6 in enterprise environments through a structured, hands-on approach. It begins with foundational routing using OSPFv3 in a multi-area design, then expands into multi-protocol environments with EIGRP for IPv6 and eBGP between autonomous systems. As you progress, you will apply key routing control techniques such as filtering, summarization, and redistribution to manage and optimize IPv6 route propagation across domains. The learning path concludes with IPv6 transition technologies, including NAT64 and IPv6 tunneling, showing how IPv6 networks integrate with existing IPv4 infrastructure during real-world migration scenarios.

Cisco has been at the forefront of developing a suite of standalone tools for data center networking, collectively known as the Day 2 Operations Suite. Recently, Cisco has initiated the integration of these tools into a unified interface called NEXUS Dashboard, providing a consolidated view and shared data repositories for enhanced application correlation. This Learning path is designed specifically for those administrators that need to perform and manage the day to day upkeep of the NEXUS Dashboard product. The learning path will include videos, article and a hands on lab going over what a typical admin would need to setup on NEXUS Dashboard. We will cover whats new with NEXUS Dashboard 3.2, creating routes for the management and data networks, creating syslog server, remote NFS and SFTP storage, creating backups, and upgrading the version. We will also go through remote authentication with radius, creating users and roles, and Intersight configuration. Finally we will bring up 2 ACI simulators and onboard the ACI fabrics to the NEXUS Dashboard platform.
