How do you design a resilient network for thousands of employees, dozens of branches, and dual data centers before buying a single switch? When should you choose OSPF, EIGRP, or service-provider grade IS-IS? How do you migrate a live enterprise to IPv6 (Dual Stack, 6RD, NAT64/DNS64), size PoE budgets and campus oversubscription, architect Cisco SD-Access and Catalyst SD-WAN fabrics, choose between DMVPN Phase 3 and tunnel-less GET VPN, align end-to-end QoS and Multicast (SSM / BIDIR-PIM / Anycast RP), and connect to AWS/Azure with Cloud OnRamp? Master enterprise network architecture step by step.

Lessons are taught live in Azerbaijani and Russian.
Every lesson starts with a concrete business requirement (SLA, budget, scale, security) and guides you through selecting the right topology and protocol. Concepts are illustrated with clear SVG diagrams, step-by-step protocol animations (IS-IS, BGP Confederations, GET VPN, SD-Access, SD-WAN OMP, NAT64, BIDIR-PIM, MDT gNMI), sizing formulas, and reference Cisco IOS XE design templates.
The golden rule (R1)
Every architectural concept—from hierarchical addressing and campus fabrics to BGP confederations, IS-IS levels, GET VPN encryption, and gNMI streaming telemetry—is explained from the ground up without unexplained jargon. Each of the 8 sections concludes with a comprehensive hands-on Architecture Design Practicum.
Full 8-section curriculum (80 lessons)

comparing NETCONF, RESTCONF
and gRPC/gNMI, designing Model-Driven Telemetry (Periodic vs. On-Change subscriptions, Dial-Out vs. Dial-In modes)
cloud service (IaaS/PaaS/SaaS) and Hybrid/Multicloud architectures
designing public cloud connectivity to AWS
Azure, and GCP (IPsec VPN, Direct Connect / ExpressRoute / Cloud Interconnect, MPLS Cloud Access)
Cisco SD-WAN Cloud OnRamp for SaaS and Multicloud
300-420 ENSLD exam strategy
and the Enterprise Architecture Capstone Project
What you can do after the course
Create complete High-Level (HLD) and Low-Level (LLD) enterprise network architectures: design hierarchical IPv4/IPv6 addressing plans and zero-downtime IPv6 migrations (Dual Stack, 6RD, NAT64/DNS64), architect resilient campuses (Routed Access, StackWise Virtual, Cisco SD-Access, and Fabric Wireless), select and scale OSPF, EIGRP, IS-IS, and BGP (Route Reflectors and Confederations), design global WANs with Cisco Catalyst SD-WAN, DMVPN Phase 3, MPLS L3VPN, and GET VPN, engineer end-to-end QoS and Multicast (SSM, BIDIR-PIM, Anycast RP), design multicloud interconnects to AWS/Azure/GCP, and architect YANG / gNMI streaming telemetry.
Alignment with Cisco CCNP Enterprise (300-420 ENSLD) Certification
This course covers 100% of the official blueprint objectives for the 300-420 ENSLD (Designing Cisco Enterprise Networks) exam. Passing 300-420 ENSLD earns the Cisco Certified Specialist – Enterprise Design certification and, combined with the 350-401 ENCOR core exam, fulfills all requirements for the full CCNP Enterprise certification.
Students join the lesson live. At the end of each lesson, students are sent a video recording of the class.
02
Homework
Every assignment is based on the topic covered in the webinar. Homework helps you reinforce the material and understand it better.
03
Working with a mentor
The teacher stays in touch with the group both during the course and outside class. Any questions get answered right away.
04
Portfolio
During the course you'll complete several projects on different topics — they'll show employers what you can do.
Self-paced learning
The full curriculum in your personal account
80 topics with theory, examples and practice. 13 of them are free (marked in the program), the rest come with a subscription. Interactive lessons with slides and coding trainers: 79.
🔒 Capstone Project: Full Architectural Design of a Global Enterprise Network (HLD + LLD)
Group and individual classes include a teacher, homework review and a certificate. The subscription gives you materials, exercises and progress tracking at your own pace, without teacher feedback.
