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
The CCNA 200-125 exam includes OSPF as one of several routing protocols (RIP, EIGRP, OSPF, BGP). The new CCNA 200-301 has OSPF, and OSPF only. This post details how to take advantage of some Packet Tracer files to re-create the
This latest OSPF Enabler exercise asked you to configure four routers in a three-area design. As usual, the exercise asks for different styles of OSPFv2 network commands, for no other reason than to give you a variety of exercise. This
In this latest OSPF Enabler exercise, you’ll configure a network of four routers with three areas. As always, the idea is simple: In one exercise, you’ll get to configure about 10 different OSPFv2 network commands, with different requirements for each.
This latest OSPF Enabler exercise asked you to configure four routers in a two-area design. As usual, the exercise asks for different styles of OSPFv2 network commands, for no other reason than to give you a variety of exercise. This
Time for another OSPF Enabler exercise. The idea is simple: In one exercise, you’ll get to configure about 10 different OSPFv2 network commands, with different requirements for each. Just getting in some reps on some skills that need to be
The first OSPF Enabler exercise asked you to configure three routers, specifically to add the OSPFv2 network commands. This post lists the answers – simple enough.
Have you mastered how to configure OSPFv2 yet? If not, look at this exercise that sets up a series of problems for you. In one exercise, you’ll get to choose how to configure about 10 different network commands, with
Can you configure OSPFv2 without the network command? Today’s post gives you the answers to a recent CLI Lab that lets you practice OSPF interface configuration. Check out the lab, create your answer, and check back here to compare.
