Border Gateway Protocol (BGP) Foundations
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.

Cisco ACI
Cisco ACI is a policy-driven CLOS or Spine/Leaf based switching fabric utilizing layer 3 ECMP routing in the underlay and VXLAN encapsulation in the overlay to transport layer two and layer three traffic East/West across the fabric and North/South in and out of the fabric. ACI consists of the Application Policy Infrastructure Controller (APIC), a centralized controller that manages all aspects of the ACI fabric. The leaf switches are ToR switches that provide connectivity between servers and external networks, and the spine switches are Layer 3 switches that provide ECMP high-bandwidth connectivity between leaf switches. An ACI fabric can be expanded East/West by adding leafs, cabling to the spines, and registering them. ACI was designed to operate as "One Big Switch" (like a chassis-based NEXUS 7K) with the controllers acting like the Supervisors, the spines as fabric modules, and leafs acting as blades. We can decouple these elements from the chassis and place them anywhere in the data center by taking this approach. The leafs (blades) can be placed anywhere in the data center, so you are not limited to a chassis.

Open Shortest Path First (OSPF) Foundations
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.

Cisco DCNM and NDFC
Data Center Network Manager (DCNM), now superseded by Nexus Dashboard Fabric Controller (NDFC), is Cisco's version of an EVPN fabric controller. DCNM, or NDFC, has three essential primary components. Spines that act like physical aggregation points for all of the leaves. Leaves provide endpoint aggregation and link to the spine. The last essential component is the controller, which in the case of DCNM is a single device or HA pair, and for NDFC, it is a Nexus Dashboard cluster with a loaded NDFC application.
In most cases, DCNM or NDFC will utilize OSPF for the underlay and VXLAN EVPN with MP-BGP as the overlay on Nexus 9000 switches. These fabric controllers are easier to use than similar fabric technologies on smaller to medium size networks, as most variables work out of the box without needing to change them. To what is known in the industry as a point and click your way to happiness.

Cisco NEXUS Dashboard
Previously, the Cisco day 2 operations suite of MSO, NAE, NIR, and NIA ran separately on computing as a .ova in vSphere or on the APIC as an application. The architecture never allowed for sharing data between the apps or correlations with errors and telemetry views of packet loss. With the roadmap moving, we had applications and a shared data lake for all applications to draw from and correlate between application errors, changes to the policy, and deep flow telemetry, all visual as an epoch.
For all the applications to run and have sharable databases, Cisco NEXUS Dashboard (ND) was created. The ND platform allows all the Cisco Day 2 apps and third-party applications to run on a single appliance. Secondly, the ND has to be an expandable CPU and storage-intensive platform; today, the platform can scale with 3 master nodes and 4 worker nodes with the apps and their data residing on the ND cluster. As ND matures, more ND servers can join the cluster, and they can be separated regionally if within TTL requirements to distribute applications and provide DR strategies.

Exploring Cisco NEXUS Dashboard
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 new to networking or new to the NEXUS Dashboard product. Future learning paths will go into more detail about operating and implementing the NEXUS Dashboard platform.

Core Routing Fundamentals
Before a core network can provide route services and traffic engineering, it must first establish basic transport connectivity between its nodes. In this course, you will learn how interior routing protocols are used to establish dynamic routing within the core, how MPLS technology is used to enhance packet transport across the underlay, and how Segment Routing is changing the way we think about transport paths. In each module you will watch a brief video describing the underlying technology and then walk through a hands-on lab to dive deeper into the relevant protocols and configurations that make underlay routing work.

Exploring Cisco NEXUS Dashboard Insights
The NEXUS Dashboard Insights service is a powerful tool that revolutionizes network telemetry utilization. Transforming raw data into actionable insights significantly reduces downtime and enhances overall network performance. This service leverages advanced analytics and artificial intelligence to provide visibility for real-time network operations. This means that IT administrators can see what's happening in the network as it happens, allowing them to address issues before they escalate.
One key benefit of NEXUS Dashboard Insights is its ability to resolve issues proactively. Instead of waiting for problems to occur and then reacting, the tool identifies potential issues early on and provides recommendations for resolution. This proactive approach not only minimizes disruptions but also ensures that the network runs smoothly and efficiently.
Moreover, NEXUS Dashboard Insights offers a comprehensive understanding of the network. It analyzes various aspects of the network, from performance metrics to security threats, and presents this information in an easy-to-understand format.
