Cisco Networking: Layer 2 Technologies
This Learning Series covers several key network engineering concepts, including VLANs and Trunks, EtherChannels, and Spanning Tree Protocol (STP). Through practical labs and real-world scenarios, you'll gain hands-on experience in configuring and managing resilient networks. The journey begins with VLANs and trunking, where you'll learn about network segmentation. Next, you'll explore EtherChannels to enhance link aggregation and redundancy. Finally, you'll master Spanning Tree Protocol to prevent network loops and optimize performance. Ideal for aspiring network engineers, IT professionals, or anyone looking to expand their knowledge of contemporary network infrastructure.

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 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.

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.

Passive Optical Networks (PON)
This learning series will explore Passive Optical Networks (PON). PON is a fiber-optic communication system typically deployed to deliver high-speed internet, TV, and phone services to homes and businesses. It uses a single optical fiber that splits passively (without powered equipment) to connect multiple users. This technology is efficient, cost-effective, and reliable because it reduces the need for active electronic components in the network, lowering maintenance and energy costs.
Learning Series
Core Routing Fundamentals
Before a core network can provide advanced 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.
