Hi Jeremy! Thanks for all this labs! Really helpful. I have a question. I did the same configuration that you did but the pings from one router to another router's interface doesn't work...Why?
Weirdly, I was having the same issue after configuring the Routers like the video. I could ping from R4 to R2's G0/0 interface and from R5 to R3's G0/0 interface. All received the advertised OSPFv3 routes, as well as the R1's Default Route to the internet. For whatever reason R2's G0/1 interface was/is acting up; even though there are no errors. After configuring everything, I saved the running config of R2 to the starting config, powered down the router and powered it back up again. Once it was up and running, I pinged from R2 to R5 - Success. Did the same to R4 - Success. Tried pinging from R4 to R5 - Success. Vice-versa? Success. Powering down R2 and powering back up again seems to fix whatever weirdness is occuring with the device's interface not being available.

Great video! The default static route did not show up in my network like in yours.

Hi Jeremy can u please make a video on understanding ipv6 address types, eui64,slaac and ndp I am having trouble understanding those concept.
Sure I'll try to make a tutorial, maybe I can release it next weekend.
@@JeremysITLab thank you so much.
Thanks for your devoted time J, practice underway - appreciated
Thanks for the comment, I the lab was helpful!
Thank you for this lab! its very useful please share more videos with us
Thank you, I will keep making videos!
R5 not ping to R4.. please correct me
What steps did you take to troubleshoot the issue?
