In this comprehensive and exhaustive techtorial on Packet Tracer activity 2.6.6 (Verify Single-Area OSPFv2) we take a deep dive into the the new Cisco Networking Academy CCNAv7 Enterprise Networking, Security, and Automation (ENSA) course curriculum! In this techtorial you will learn how to verify and validate your OSPFv2 configuration and installation through the use of commands like 'show ip route ospf', 'show ip ospf interface', 'sh ip protocols', 'show ip ospf neighbor detail', and many, many more. All commands that you as a network engineer in an OSPFv2 environment should have as part of not only your verification and validation toolbox, but in your troubleshooting toolbox as well. This techtorial/Packet Tracer activity is all done running Packet Tracer version 7.3.0 which was just released this week and is the MINIMUM version you can use for any of the new CCNAv7 curriculum activities! Be sure to leave your feedback and questions below and I hope I have earned the privilege of your time! Enjoy!

In this comprehensive and exhaustive techtorial on Packet Tracer activity 2.7.1 (Single-Area OSPFv2 Configuration Challenge) it is time to buckle your OSPF chinstrap as we take a deep dive into the the new Cisco Networking Academy CCNAv7 Enterprise Networking, Security, and Automation (ENSA) course curriculum! In this techtorial you will learn how to take all of the knowledge from the previous OSPF Packet Tracer activities (and Chapter #2 of the course text!) and implement an OSPFv2 routing domain. You will definitely need your OSPF tool box and all of its tools for this activity! You will be asked to configure OSPF Router ID (RID) values, OSPF priority values, enable OSPF on interfaces both through the 'ip ospf' command and through the use of the 'network' command, you will enable passive interfaces on LAN-facing interfaces, create a default static route and then originate that default static route into your OSPF routing domain, and much more! I will even go over the error in this activity where you are asked to use the 'auto-cost reference-bandwidth' command so that GigabitEthernet interfaces have a cost of 10 and FastEthernet interfaces have a cost of 100 and explain how/why the grading engine gets this wrong. This techtorial/Packet Tracer activity is all done running Packet Tracer version 7.3.0 which was just released this week and is the MINIMUM version you can use for any of the new CCNAv7 curriculum activities!

In this comprehensive and exhaustive techtorial on Packet Tracer activity 2.5.3 (Propagate a Default Route into OSPFv2) we take a deep dive into the the new Cisco Networking Academy CCNAv7 Enterprise Networking, Security, and Automation (ENSA) course curriculum! In this techtorial you will learn how to create a default static route and then advertise/originate that default static route into OSPFv3. In addition, we go over the various configuration options that accompany the 'default-information originate' command such as the 'metric', 'metric-type', and 'always' options and discuss use cases for each one. Each one of those options is also configured on real Cisco ISR G2 routers and all of the validation and verification commands needed are demonstrated. We also talk about the default metric value for a default route when it is advertised/propagated into OSPFv2. This techtorial/Packet Tracer activity is all done running Packet Tracer version 7.3.0 which was just released this week and is the MINIMUM version you can use for any of the new CCNAv7 curriculum activities!

In this comprehensive and exhaustive techtorial on Packet Tracer activity 2.4.11 (Modify Single-Area OSPFv2) we take a deep dive into the the new Cisco Networking Academy CCNAv7 Enterprise Networking, Security, and Automation (ENSA) course curriculum! In this techtorial you will learn how to manipulate OSPF timer values like the HELLO and DEAD intervals, you will learn the semantics behind which values need to match in order for an OSPF adjacency to be established and to be maintained, we will take a deep dive into Layer 3 traffic engineering with OSPF and discuss the reasons why manipulating the bandwidth setting is not always the correct way to approach this task, and we discuss how to validate and verify your work. This techtorial/Packet Tracer activity is all done running Packet Tracer version 7.3.0 which was just released this week and is the MINIMUM version you can use for any of the new CCNAv7 curriculum activities!

In this comprehensive and exhaustive techtorial on Packet Tracer activity 2.3.11 (Determine the DR & BDR) we take a deep dive into the the new Cisco Networking Academy CCNAv7 Enterprise Networking, Security, and Automation (ENSA) course curriculum! In this techtorial you will learn why OSPF needs to have a DR & BDR on broadcast/multi-access networks - and why you don't need one on point-to-point network types, which multicast addresses are used for communication with the DR, BDR, and DROTHERS, how to manipulate and influence the election of the DR & BDR, how to configure the 'ip ospf priority' command, why the DR/BDR election process is not preemptive, how to debug OSPF adjacency events, and how to validate and verify your DR and BDR configuration and status. We also go over the John T. Moy OSPF RFC, RFC 2328, and I introduce you to the two (2) legendary texts on the OSPF routing protocol - one by the creator, John T. Moy, and the other by routing legend, Jeff Doyle. Both books are "must haves" for any serious/professional network engineer who is working with OSPF. This techtorial/Packet Tracer activity is all done running Packet Tracer version 7.3.0 which was just released this week and is the MINIMUM version you can use for any of the new CCNAv7 curriculum activities!

In this comprehensive and exhaustive techtorial on Packet Tracer activity 2.2.13 (Point-to-Point Single-Area OSPFv2 Configuration) we take a deep dive into the the new Cisco Networking Academy CCNAv7 Enterprise Networking, Security, and Automation (ENSA) course curriculum! In this techtorial you will learn about the importance of the OSPF Router ID (RID) and how to change the value should the need arise, we cover three (3) different methods for configuring the OSPF process to run on an interface, how to "passive" interfaces so that OSPF HELLO messages are not sent, we discuss the differences between the Broadcast and Point-to-Point network types, and then we run a series of CLI commands to validate and verify our OSPF configuration. This is all done running Packet Tracer version 7.3.0 which was just released this week! Be sure to leave your feedback and questions below and I hope I have earned the privilege of your time!
