The Five OSPF Details You Need to Know to Pass Your CCNP / BSCI Certification Exam

The CCNP/BCSI certification exam is one of the most difficult tests you’ll ever have to take as an IT candidate, which makes it all the more important that you study hard and know your material inside and out before going into the test. One of the toughest sections on this test happens to be in OSPF, which stands for Open Shortest Path First. Fortunately, there are only five details that you need to know in order to pass this part of the test—and they’re all covered here in this blog post by Cisco expert Wendy Haynes.

OSPF Packet Types
Open Shortest Path First (OSPF) is a routing protocol used in IP networks to determine the best paths for data packets to travel between nodes. It is an important topic to master for the Cisco CCNP / BSCI certification exam, so it’s important to understand the different OSPF packet types and their functions. These five OSPF details are essential to passing the exam:

LSAs
Open Shortest Path First (OSPF) is a link-state routing protocol used to route packets between different networks. It does this by broadcasting Link State Advertisements (LSAs) which contain the routing information for each connected device. In order to pass your CCNP / BSCI certification exam, you need to understand five key details about LSAs. These are: Type, ID, Age, Options, and Checksum. Each of these values must be correct in order for OSPF to operate correctly. Knowing the purpose of each field and how it affects the routing table can help you successfully complete the exam.

Adjacencies
Establishing adjacencies is a critical part of the Open Shortest Path First (OSPF) routing protocol, and it is important to have a good understanding of how these are formed in order to pass your CCNP / BSCI certification exam. Adjacencies occur when two OSPF routers exchange Hello packets and form a direct link between them. During this process, the routers must agree on certain parameters such as the area type, authentication method, and Hello/dead intervals. Once the routers establish an adjacency, they can then begin exchanging routing information. To prepare for the CCNP / BSCI certification exam, it is important to review how adjacencies are formed, the role of each router in the formation process, and how routing information is exchanged between adjacent routers.

Route Calculation
OSPF is an important protocol used in Cisco networks and a key component of the CCNP / BSCI Certification Exam. To pass this exam, you must understand the details of how OSPF routes are calculated. The OSPF routing algorithm works by building up a link-state database which contains all the topological information of the network. From this information, it builds a shortest path tree to calculate the optimal route for each destination in the network. It uses a complex process involving different metrics to determine the best path for each route. Additionally, it can reroute traffic quickly if there is a link failure in the network. Knowing how OSPF works and how routes are calculated is essential to understanding how to effectively build and maintain a successful Cisco network.

DR/BDR
The Open Shortest Path First (OSPF) protocol is one of the most important components of a successful Cisco Certified Network Professional (CCNP) / Building Scalable Cisco Internetworks (BSCI) certification exam. In order to pass this exam, it’s important to have a thorough understanding of how OSPF works, including the five key details about the Designated Router (DR) and Backup Designated Router (BDR). These are two special routers that are responsible for managing the connections between other routers in an OSPF network. By understanding the role and configuration of these two routers, you’ll be able to successfully navigate the CCNP/BSCI certification exam.
