[Cisco CCNA 640-875 SPNGN1]
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!"
[Cisco CCNA 640-878 SPNGN2]
1. Welcome to SPNGN2: Cisco Certification and Getting the Most from this Course (00:14:22)
If you need a little "spunk" to get going with this course, this Nugget is for YOU! Jeremy discusses the CCNA Service Provider certifications, talks about the "CBT Nuggets way" of training, and how you're able to get the most from this course.
2. IP NGN: Service Provider Architecture (00:20:36)
WATCH THIS FIRST! In this Nugget, Jeremy focuses on the "Service Provider Big Picture," providing an overview of service provider to customer connectivity and interconnects. In addition, you'll understand what differentiates an IP Next Generation Network (NGN) Service Provider from a traditional service provider. This Nugget is a foundation stepping stone to the remainder of the course.
3. IP NGN: The Core Protocols of the Service Provider (00:26:16)
Think of this as the "sneak peek" of the entire course. Based on a panel discussion with one of the largest service providers in the US west coast region, Jeremy has compiled a Most Valuable Protocol (MVP) listing of key technologies and provides an overview of each in this Nugget. Topics include IP connectivity, internal ISP routing (OSPF, IS-IS), external ISP routing (BGP), MPLS, and mBGP.
4. IP NGN: The Service Provider Router Dream Machines (00:19:10)
Moving into the service provider environment introduces you to completely new lines of carrier-grade equipment. This Nugget introduces you to the course and gives you some visuals and specification on the types of equipment you can expect to see. Included here is the ASR 1000, 9000, XR 12000, and CRS series of equipment.
5. VLAN: What is a VLAN? (00:24:24)
In Jeremy's Network Survival Guide, VLANs make the No. 2 most valuable technology! In this Nugget, you'll learn the core concepts of VLANs, see multiple practical examples of VLANs-in-action, and see the concepts behind the complex QinQ (802.1ad) double-tagging method used in many service providers today!
6. VLAN: Layer 2 Configuration (00:25:14)
VLANs, in and of themselves, are a fairly simple concept and configuration. It's all the other VLAN-integrated network technology (STP, routing, tagging, etc.) that makes them seem complex. Because of that, Jeremy has broken down the VLAN configuration into multiple Nuggets, and this one focuses on VLAN creation, switchport configuration, trunking configuration, and even a full GNS3 topology build complete with EtherSwitch modules and Virtual PC Simulators (VPCS)!
7. VLAN: Layer 3 Configuration - Router on a Stick (00:27:08)
This is more than a normal Nugget... it's an adventure in routing! By time you're through here, you'll be running to configure VLANs, client PCs, sub-interfaces, and isolated management VLANs, all while singing "All By Myself" (yes, you have to watch this Nugget to understand).
8. VLAN: Layer 3 Configuration - L3 Switching (00:18:38)
While the "Router on a Stick (ROAS)" works fantastically well for smaller environments, L3 switching has become the standard for high-speed routing everywhere else. In this Nugget, Jeremy transitions your ROAS skills into a full L3 Switching configuration.
9. STP: Spanning Tree Revisited (00:25:39)
Consider this Nugget your "cram session review" of Spanning Tree Protocol (STP), originally covered in our Cisco ICND2 course as well as SPNGN1. Here, Jeremy discusses the core functionality of STP, how STP finds the best path around the network, and the flavors of STP (STP, PVST, RPVST/RSTP, MSTP).
10. STP: Configuring RSTP and MSTP (00:27:09)
The title of this Nugget says it all. You will watch and learn as Jeremy walks through the configuration of Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP) and verifies the configuration.
11. Metro Ethernet: Introducing the ME 3400 Switch (00:13:01)
As service providers trench up miles of street to run fiber optic cables, they reach customer-saturated locations such as shared office space, strip malls, and condominiums. To bring these customers into the fold, the Cisco ME 3400 series switch delivers! In this Nugget, Jeremy breaks down the placement, functions, and port types of the Metro Ethernet series of switch.
12. Metro Ethernet: Understanding and Configuring Cisco REP (00:24:12)
As the speed of communication increases the tolerance for failure seems to decrease! The once "rapid" failover of Rapid Spanning Tree Protocol (RSTP) is no longer desirable. The remedy? Cisco's Resilient Ethernet Protocol (REP)! This Nugget walks through the concepts and configuration of Cisco REP in a service provider environment.
13. Metro Ethernet: Understanding and Configuring 802.1ad (QinQ) (00:11:51)
Just when you get ONE VLAN tag down, another appears! It's QinQ! The ability to "double-tag" VLAN information on packets, typically used in a service provider environment. This Nugget breaks down the QinQ concepts, best practices, and configuration.
14. OSPF: Welcome to the World's Most Popular Routing Protocol (00:33:22)
Learning RIP may be where you begin, but learning OSPF is what you want. This routing protocol rules the enterprise environment, as well as being heavily utilized to operate the internal core of a service provider network. In this Nugget, Jeremy discusses the place of OSPF (customer or service provider), the OSPF neighborhood, and OSPF metric adjustments.
15. OSPF: Basic OSPF Configuration (00:40:16)
Walk step by step with Jeremy through a configuration of SIX different routers (running IOS and IOS-XR) for OSPF using a variety of different methods (pick your favorite)! You'll also see OSPF MD5 authentication and verification done right before your eyes.
16. IS-IS: The Routing Protocol You Never Knew (00:24:50)
If you've never heard of the IS-IS routing protocol, this Nugget is for you! IS-IS (which is the routing protocol for OSI) was originally mandated by the US government to exist in every ISP. While many ISPs have moved away from IS-IS, it has many significant advantages over OSPF that are worth considering! This Nugget covers the concepts and design behind IS-IS along with a detailed comparison of OSPF vs. IS-IS.
17. IS-IS: Configuration (00:37:32)
It's time to configure the "weird one:" the IS-IS routing protocol! This Nugget lives virtually entirely in the live interface configuring IS-IS routers, NSAP addresses, circuit-types, metrics, summary-addresses, and more!
18. BGP: Core Routing Protocol Concepts (00:29:41)
In the customer realm, BGP is a "high-level" routing protocol known and needed by few. In the Service Provider arena, it's FUNDAMENTAL. In this Nugget, Jeremy illustrates the place and usage of BGP in the Service Provider environment, covers key BGP facts, and discusses Multiprotocol BGP (mBGP or MP-BGP).
19. BGP: The Simple Metric (00:25:23)
You'll quickly find with BGP that there's nothing simple about the metric at all! Nonetheless, Jeremy does a masterful job in this Nugget guiding you through the important route attributes YOU NEED TO KNOW for BGP (Origin, AS-Path, Weight, Local Preference, and more!), along with the BGP route selection process.
20. BGP: Basic BGP Configuration (00:50:34)
BGP is awesome and (as you might expect) tremendously huge! In this Nugget, Jeremy attempts the impossible: to demonstrate base BGP configuration (including forming neighbor relationships, mBGP address-families, advertising networks, route-maps, route-policies, and more) on IOS and IOS-XR all in a single Nugget. Yes, as you might expect, you'll want to save a little extra time to view this gem!
21. FHRP: Understanding HSRP, VRRP, and GLBP (00:26:38)
Can you love it when things break? Jeremy thinks so... as long as you design it well! In this Nugget, you will explore First Hop Redundancy Protocols (FHRPs) and discover their purpose, the three different flavors (HSRP, VRRP, GLBP), and walk through a configuration on IOS and IOS-XR.
22. Services: MPLS Technology Overview and Core Concepts (00:33:05)
What service provider course would be complete without a discussion about MPLS? Label switching has become a standard issue technology in nearly every service provider in the world. In this Nugget, you will learn the functions of MPLS, the architecture of MPLS packets, and walk through a configuration and verification of MPLS on IOS and IOS-XR.
23. Services: Understanding Access Control Lists (ACLs) (00:17:03)
Access Control Lists (ACLs) are such a big topic, we decided to bridge it over three individual Nuggets. In this introduction to ACLs, Jeremy describes the many uses of ACLs (they're not just for access control), the foundation rules, and the common types (standard and extended) of ACLs.
24. Services: Configuring Standard Access Lists (00:39:20)
It's a video game adventure of sorts. (just watch and you'll understand). In this Nugget, Jeremy walks through three live scenarios of Standard ACL configuration on IOS and IOS-XR routers!
25. Services: Configuring Extended Access Lists (00:43:10)
The name describes it all! Just like the Standard ACL Nugget, you will walk through three Extended ACL implementation scenarios on IOS and IOS-XR.
26. Services: The Road to IPv6 (00:28:41)
Yes indeed, the IPv4 IP address shortage is REAL! With the rapid Internet growth occurring around the world, there will soon be severe limitations on public IPv4 addresses. As the world changes to IPv6, there will be a "middle ground" of transition mechanisms needed. In this Nugget, you'll learn about NAT444, NAT64, DNS64, 6to4, GRE, 6rd tunneling, Dual-stack, and DS-Lite.
27. IOS Maintenance: Handling IOS XR Software (00:14:19)
This final Nugget of the course focuses on IOS XR service and maintenance. By time you're done, you'll understand the difference between the three flavors of IOS (IOS, IOS-XE, and IOS-XR), the IOS-XR software release cycle, the upgrade process for PIE software packages, and disaster recovery using Turboboot.
