⚔️ Lab Challenge #13 - OSPF Adjacency Issue
Hey guys! From now on I'll try to make the labs a bit shorter because most of you find them too long. For those who like longer labs with more stuff to discover and troubleshoot: Don't worry! I'm working on something for you 👀 In today's lab, R1 and R3 are not forming a neighbour adjacency. Troubleshoot and fix the problem! ✅ When you’re done, post screenshots showing R1 and R3 successfully formed a neighbour adjacency. Good luck 🚀

Explaining the task with a video is really helpful for me.

2025 BlackFriday CCNA Exam Voucher with or without Safeguard available?
I wonder if there is already or will be an offer for a CCNA Voucher with or without safeguard (I would definitely prefer with safeguard). Any hint or feedback appreciated!

There are so much commands totaly logical. Even long ones. This one doesn’t make sense to me: Why does generating keys also activate SSH at the same time? And also: How to disable SSH? (Hopefully I don’t have to delete the keys. 🤭)

@Vithuschan Kirupakaran-Eikemper so the ssh server is also running without keys but is not operational because of the missing keys?

As i selected the wrong answer, this could be a good occasion to try „dhcpdump“ again and see it live.
