Doing labs helps you move from book-knowledge to real skills, and doing labs that repeat the same examples found in the book can be a great bridge to that effort. This next post continues our series to help you do
OSPF requires two routers to become neighbors before they can exchange OSPF LSAs and then calculate new routes. Chapter 21 of the CCNA 200-301 Volume 1 focuses on neighbor relationships. The chapter examines why some links require a Designated Router
For many years, over many different versions of the CCNA exam, Cisco included multiple IP routing protocols in the exam: RIP, OSPF, EIGRP, and even BGP. With CCNA 200-301, Cisco reduced IP routing protocols down to only one: OSPF. Chapter
I’m pretty excited about a new project called CCNA Deep Dive. I used to teach quite a bit, and this year I’ll be back on platform – but doing the teaching online rather than in person. And you can join
You studied hard for CCNA 200-125, but you know you won’t finish it before the Feb 23rd deadline. Now you’ve moved on to CCNA 200-301. Did you use my CCNA 200-125 books? Are you now using my new CCNA 200-301?
Anyone who has been pursuing CCNA Routing and Switching (R&S) over the last several months has asked themselves a simple question: Should I move on to study for the new CCNA based on the 200-301 exam that arrives Feb 24,
If you took any of the CCNA Deep Dive courses on O’Reilly, then you probably remember what this post is for. If not, you shouldn’t care! Regardless, this post is a place for anyone in the CCNA 200-301 Deep Dive
You’ve probably been using ping, traceroute, Telnet, and SSH all through your lab efforts. But maybe not. This next chapter (CCNA Vol 1, Chapter 18) looks at those tools precisely, rather than treating them a brief aside to do some
For most people, the Cisco CCNA certification has been the first certification for which you learned about two core networking concepts: LAN switching (as performed by switches) and IP routing (as performed by routers). Of course, in real life, the
CCNA 200-301 Volume 1 Chapter 16 has several good examples you can recreate in Packet Tracer (PT). This chapter focuses on IPv4 routing, both the concepts and some of the related configuration. It includes concepts and configuration for IPv4 addresses
