This CBT Nuggets SPNGN1 course truly covers a broad set of information that needs to be known in order to pass the SPNGN1 640-875 certification exam. You begin the course by understanding network fundamentals, discussing topics such as the OSI Model, switch and router functionality, and cabling standards. From there, you will move quickly into understanding the differences between IOS and IOS-XR (Cisco’s service provider-specific OS), configuration of routing protocols in both IPv4 and IPv6, network services, and device management.
Unlike most other Cisco courses, there are no pre-requisites for the SPNGN1 certification course. However, this course does move faster than most because Cisco assumes most individuals aspiring to work in a service provider role have some previous background in a technology arena. In addition, Jeremy has created a “reduced schedule” of videos for those already competing the CCENT (ICND1) or CCNA (ICND2) courses. Be sure to view the first video for the complete list!

1. Welcome to SPNGN1: Cisco Certification and Getting the Most From This Course (00:12:33)
Welcome to Cisco’s Building Service Provider Next Generation Networks (SPNGN) Part 1! In this opening Nugget, Jeremy breaks down the CCNA Service Provider paths and certifications, differentiates between CCNA Service Provider and Service Provider Ops, provides an EXTREMELY valuable «cutting corners» spreadsheet for existing CCENT/CCNA students, and walks through methods to get the most from this course!
2. IP Networks: Understanding Service Provider Network Architecture (00:37:53)
It’s your first step into the service provider world: understanding the network architecture. We start from the ground level by asking the questions, «What is a Network?» and «Who is Cisco (and why do you care)?,» and then quickly move into topics such as the Cisco Three-Tier Model and IP Next Generation Network (NGN) design (specific to service providers).
3. IP Networks: Key Network Devices (00:29:41)
Service provider networks at their core are not too much different than a typical home or business network . . . things are just BIGGER! In this Nugget, Jeremy walks through the function of the core network equipment: hubs, switches, wireless access points (WAPs), routers, and firewalls.
4. IP Networks: The Fantastic OSI and TCP/IP Models (00:36:15)
Did you know that the OSI Model was never meant to be JUST a model, but was actually a system to describe the OSI protocol (a competitor to TCP/IP)? Us neither! Find out about this and all the other intricacies of the OSI Model (including the seven layers and practical communication examples) in this Nugget!
5. IP Networks: Connections, Diagrams, and Applications (00:14:15)
In this Nugget, Jeremy explores the physical connections used by service providers to bring their customers into the ISP network. Additional topics include network diagrams, application types, and a quality of service (QoS) overview.
6. IP Addressing: The Key to IPv4 and IPv6 Addressing (00:29:04)
There’s likely no one topic more important to your career in service provider networks than IP addressing. In this Nugget, Jeremy tackles the core principles of IPv4 and IPv6 network addresses. In addition, he provides an excellent, end-to-end network communication example which illustrates the integration of IP and MAC addressing through using the Address Resolution Protocol (ARP).
7. IP Addressing: Simple Subnetting — Finding Networks (00:37:56)
Oh no! The dreaded «subnetting» topic! Never fear, CBTNuggets is here! In this Nugget, you’ll walk through the first form of subnetting: carving up networks based on network requirements (versus host requirements which is the following Nugget). Prepare to be enlightened!
8. IP Addressing: Simple Subnetting — Finding Hosts (00:17:37)
The subnetting fun continues! This Nugget is focused on creating subnets based on host requirements (for example, determine subnets based on needing 20 devices on a network).
9. IP Addressing: Variable Length Subnet Masks (VLSM) (00:21:57)
It’s the pinnacle of subnetting topics: VLSM! This Nugget actually covers two key topics: reverse engineering a subnet mask (for example, given a specific IP address and subnet mask, can you determine which network the device came from?) and variable length subnet masks (or VLSM) — finding custom subnets for each applicable part of your network.
10. IP Addressing: Host and Server IP Configuration and Testing Tools (00:30:28)
It’s time to make IP addressing very practical! In this Nugget, Jeremy works with Windows Server command-line tools (which are applicable to the CCNA Service Provider exam) to test and troubleshoot IP-based connections. Topics include static IP addressing, ping, trace route (tracert), arp, nslookup, and Wireshark (packet sniffing).
11. Switching: Welcome to the Ethernet World (00:19:33)
We now enter the Layer 2 domain of the Cisco world: Switching! In this Nugget, Jeremy masterfully lays the foundation that networks have been built on for decades: hubs, bridges, and switches. This Nugget concludes with an excellent discussion of collision and broadcast domains, along with following a network frame through a switch environment with a «Day in the Life of a Switch.»
12. Switching: Working with the Cisco IOS (00:27:53)
While this topic directly relates to switching, it goes far beyond just the switching domain — into nearly every piece of equipment Cisco manufactures! It’s the Cisco Internetwork Operating System (IOS)! This Nugget goes through the foundation navigation, help features, and modes of the IOS software.
13. Switching: Base Switch Configuration (00:44:02)
With the foundation IOS navigation concepts being laid in the previous Nugget, you’re ready to explore the base IOS configuration of a switch! In this Nugget, Jeremy walks through the configuration of the hostname, passwords, IP addressing, interfaces, and logon banner on a Cisco switch.
14. Switching: Spanning-Tree and Flex Links (00:38:31)
Spanning-Tree Protocol (STP) is one of the most misunderstood (or NOT understood) concepts in all the Cisco CCNA programs combined. Well, not after THIS Nugget! In here, you’ll look at the issue of broadcast storms, STP operation and configuration, and the STP «bypass» Flexlink (good for Service Provider environments needing to avoid STP).
15. Routing: Did Cisco Invent the Router? (and other routing mysteries) (00:25:39)
Welcome to the routing world! This Nugget focuses on the foundations of routing by answering the question, «What is routing?» and walking through a end-to-end communication scenario. In addition, Jeremy analyzes the physical aspects of a Cisco router. And yes, Jeremy does finally answer the question, «Did Cisco really invent the router?» in this Nugget.
16. Routing: Base Configuration from IOS to IOS-XR (00:42:07)
Wow! Things are moving fast now! Get your pens ready as Jeremy dives head first into base router configurations. Initially, things begin in the standard Cisco IOS (working on a customer premise router) and quickly move into the IOS-XR. You will learn key differences between IOS and IOS-XR, from architectural changes to the administrator command-line interface.
17. Routing: Implementing Static Routing (00:18:35)
Our base router configuration is handled . . . now it’s time to route! This Nugget covers one of the most fundamental routing methods available: static routing. This will be implemented on both a customer premise router (default route — IOS) and carrier router (ISP — IOS-XR).
18. Routing: RIP Lives On! (00:18:47)
RIP is one of the most . . . «seasoned» routing protocols that exist in the networking realm and provides a GREAT introduction to routing protocols in general. In this Nugget, Jeremy walks through the place of RIP (and dynamic routing protocols), as well as the configuration of RIP on live equipment.
19. Routing: EIGRP Concepts (00:30:04)
EIGRP is Cisco’s creation and it is truly a work of art. In this Nugget, Jeremy breaks down the EIGRP concepts: key benefits, terminology (such as successor, feasible successor, tables, etc…), neighbor relationships, and metric.
20. Routing: EIGRP IPv4 Configuration (00:42:30)
Now that you’ve seen the concepts, it’s time to get our hands dirty configuring EIGRP. This Nugget walks through the full configuration of EIGRP for IPv4 on IOS and IOS-XR.
21. Routing: EIGRP IPv6 Configuration (00:19:42)
The EIGRP configuration fun continues as we move to IPv6. In this Nugget, Jeremy uses the same topology as the previous IPv4 configuration and implements an IPv6 configuration.
22. Routing: Advanced Routing Concepts (00:23:57)
In the CCNA Service Provider world, we waste no time in moving to the «advanced world» of topics! This Nugget is dedicated to understanding three key topics: Route Redistribution, Virtual Routing and Forwarding (VRF), and Generic Routing Encapsulation (GRE).
23. IP Services: NAT Concepts (00:20:52)
Network Address Translation (NAT) is likely the most widespread and essential IP service in the networking realm. In this Nugget, Jeremy discusses the core of NAT, the various methods of NAT (static, NAT Overload/Port Address Translation (PAT), and dynamic), and the key NAT terms and locations (such as inside local, outside global, etc.).
24. IP Services: NAT Configuration (00:27:58)
You’ve got the NAT Concepts (previous Nugget), now it’s time to put some meat on it! This NAT Configuration Nugget moves from static NAT to NAT Overload (aka PAT) to an interface and finally finishes with NAT Overload to a pool of addresses (NAT pool).
25. IP Services: DHCP for IPv4 and IPv6 (00:18:57)
What network doesn’t use DHCP? Well . . . IPv6 networks, if you prefer! In this Nugget, Jeremy discusses the evolution of DHCP from the IPv4 realm to IPv6, and covers the configuration of DHCP on a Cisco device.
26. IP Services: ICMPv4, ICMPv6, and DNS (00:25:13)
ICMP . . . it’s more than PING (who knew?)! This Nugget explores the functions of ICMP in both the IPv4 and IPv6 protocol, and the core of DNS functionality — and relates it all to the Cisco Network Technician.
27. SP Transport: Service Provider Optics (00:22:52)
Get ready to see the light! In this Nugget! Jeremy discusses the «core network» connectivity of service providers using SONET/SDH (Carrier Ethernet), and then dives into Dense Wavelength Division Multiplexing (DWDM) and the wonders of the light spectrum. Wrapping up, you’ll learn the progression of Ethernet from 10 to 40 to 100Gbps.
28. SP Transport: Service Provider «Last Mile» (00:25:07)
The «Last Mile» typically refers to the final leg of cabling (usually copper) that reaches a customer. In this Nugget, Jeremy jumps down from the optical SONET ring into the customer connection. Topics are heavily focused on DSL and Cable connection, as well as Frame Relay, ATM, and FTTx (Fiber to the X).
29. Security: Service Provider Security Foundations (00:20:44)
Service provider security can be an enormous topic! However, at the CCNA Service Provider level, Cisco has chosen to focus primarily on the concepts of port security, management and control plane defense, and the role of IPSec — which are all covered in this Nugget.
30. Security: Security with AAA (00:23:07)
Enabling Authentication, Authorization, and Accounting (AAA) adds an entirely new dimension of user security to your devices, allowing for on-box and off-box (TACACS+ / RADIUS) methods. In this Nugget, Jeremy defines what AAA can do for you and its configuration.
31. Device Management: SNMP, IP SLA, and Netflow (00:20:12)
In recent years, Cisco has made active device monitoring a large topic on many certification exams. Rightly so! This comprises much of the day-to-day work of a Cisco engineer! This Nugget breaks down the key monitoring technologies: SNMP (active monitoring), IP SLA (active testing and simulation), and Netflow (flow-based tracking).
32. Device Management: NTP, Syslog, and SPAN (00:22:21)
The device management continues! This Nugget adds additional tools to your tool belt as Jeremy unpacks the Network Time Protocol (NTP), Syslog (centralized logging functions), and the Switchport Analyzer (SPAN).
33. Device Management: Managing IOS Software and Configuration Files (00:17:57)
Cisco devices have many of the same components as a normal Personal Computer (PC). Knowing how to work with these components, upgrading software, and backing up configurations is the primary focus of this Nugget.
34. Device Management: Reaching Out for Help From Cisco (00:11:34)
Everybody needs a little help sometimes . . . and that’s why this Nugget is here! In this Nugget, Jeremy unpacks the Smart Call Home feature, opening a Cisco Technical Assistance Center (TAC) request, and even «becoming a Google ninja!»
