Are you preparing for the Cisco Certified Entry Networking Technician (CCENT) exam? One of the most important topics on the exam is routing protocols. This blog post will discuss the three main routing protocols for the CCENT exam: OSPF, EIGRP, and RIP. We’ll review the different features of each protocol, as well as their advantages and disadvantages. We’ll also look at how to configure each protocol in a small network. By the end of this blog post, you should have a good understanding of the three main routing protocols for the CCENT exam.
Routing Information Protocol (RIP) is a distance-vector routing protocol that uses hop count as its metric. It is an interior gateway protocol which is used within a single autonomous system and works by broadcasting information about known network destinations to all its connected routers. RIP can be used for both IPv4 and IPv6, but the latter version is rarely seen in practice due to its lack of security features. RIP is one of the most widely used routing protocols for the CCENT exam and it provides a straightforward way of connecting different networks.
Open Shortest Path First (OSPF) is one of the most important routing protocols for the CCENT exam. OSPF is an Interior Gateway Protocol (IGP) and has been designed to route IP packets within a single Autonomous System (AS). It uses a link state algorithm to build and maintain its routing table, which allows it to quickly respond to changes in the network.
Unlike RIP, OSPF is capable of handling multiple class networks as well as Variable Length Subnet Masks (VLSM). This allows you to break up your network into smaller, more efficient pieces. OSPF also allows you to assign priorities to different paths, which can be helpful when creating redundant links.
It’s important to note that OSPF is a classless protocol, which means that it can support Variable Length Subnet Masks (VLSM). This allows you to break up your network into smaller, more efficient pieces.
Overall, Open Shortest Path First (OSPF) is an essential protocol for the CCENT exam and understanding how it works will help you better manage your networks.
