OSPF Configuration & Show Commands - Practical OSPF
Ғылым және технология
In this video we walk through an OSPF configuration together and I discuss the commands I am using and their effect. All the while showing you the various show commands you would use to validate OSPF's operation on Cisco routers. Below are the commands we'll be using in this live lab demonstration:
Show Commands:
show ip protocols
show ip ospf interface [brief]
show ip ospf neighbors
show ip ospf database
show ip ospf rib [detail]
show ip route [ospf]
Configuration Commands:
router ospf {process ID}
router-id {router-id}
Adding Interfaces to OSPF:
network {network ID} {wildcard mask} area {#}
ip ospf {process ID} area {#}
This is lesson 5 of my OSPF Deep Dive series. The entire series is available here on KZread:

Hi, a software developer here. Thanks to your lessons, I've gone from a complete noob in networking to being able to configure our small business's entire office network in the span of a few months. For a video learner like me, this is by far the best learning resource on networking subjects anywhere on the entire internet.
Ed,what you do fo improve the general understanding of networking is TOP-NOTCH. Please dont forget that. Your'e fixing the world. Your'e an absolute savior.

You are totally right. He is the master; he explains networking concepts in a simple and detailed manner. Waiting for the OSPF network types.
At 21:30, I really like how you illustrated that the network command is configuring any INTERFACE that meets an address range (or specific address) into an OSPF process, and not necessarily specifying a network to put into OSPF. The fact that you used /16 to group them, but they were still understood to be /24 was a great illustration of that. I had been under the 'common misconception' you alluded to earlier. In fact, I believe that misconception was exactly what I was taught in school. Lol. Thanks for clearing that up in a practical, visual, way. 👍💯. Your contributions and effort are monumental.

Hi Ed, I've followed a few videos over the years but never a complete series. After obtaining the CCNP Data Center I decided to review everything to consolidate the topics. Your explanation of OSPF is absolutely the best online and better than any paid courses I've taken over the years! I'm still a junior figure in this field (I've been working for almost 3 years) but thanks to studying and your videos my skills continue to grow quickly. We share the same teaching philosophy: helping others where we have had to struggle to understand things and from your teaching method and attention to detail we understand how much this makes the difference. Thank you very much, greetings from Italy.
