Ad Hoc Labs – OSPF (Volume 1 Part 6)
Over at my YouTube channel, I’ve created some labs that exist solely as videos plus a Cisco Packet Tracer .pkt file. The video begins with instructions. Then pause the video, download the .pkt file, and complete the lab using CPT. If you want more guidance or insights, watch the rest of the lab for commentary and a demo.
The Ad Hoc Labs have been popular, along with the Config Labs (labs described in blog posts). But it occurred to me that if you come to the blog site, do not visit my YouTube channel, and do not notice the Ad Hoc Labs, you could miss out on them! So I’ve made a series of posts introducing the current topics of Ad Hoc Labs on my YouTube Channel. This one introduces labs related to content in Volume 1, Part 6 of the CCNA Official Cert Guides. Enjoy!
Ad Hoc Labs for This Book Part
OSPF logic is far more difficult than the configuration. So this lab begins with everything configured! Your job: Figure out what OSPF is doing behind the scenes by exercising the many options on the show ip ospf command.
By default, OSPF elects a DR and a BDR on Ethernet links with at least two routers. Who wins, and why? In this lab, you get to practice your skills in predicting the outcome of the elections!
OSPF defines a Hello and Dead Interval. They have defaults, but you will likely want to improve those settings. But you can just get them completely wrong – so explore the values and practice with this lab!
The lab begins with four pairs of routers that SHOULD be neighbors, but are not – and you need to figure out what’s wrong and fix it.
Types of CCNA Labs: Blog + Youtube

Config Labs that have been enhanced to not only support performing the lab with Cisco Modeling Labs (CML), but also to support performing the lab using the Free edition of CML. Learn more in the introductory CML-Free lessons at my CML-Free YouTube playlist.
