What is NSSA Not So Stubby Area in OSPF? Not So Stubby Area (NSSA) is a type of Open Shortest Path First (OSPF) area that allows for limited advertisement of external routes. NSSA was designed to address the problem of stub areas, which do not allow for the exchange of external routes. However, NSSA has … Read more
In the dynamic landscape of networking, optimizing routing protocols is crucial to ensure efficient data flow. Open Shortest Path First (OSPF) is a popular routing protocol that allows routers to communicate and exchange routing information. One of the key elements in OSPF configuration is the concept of a passive interface. In this article, we’ll delve … Read more
What is OSPF in Networking? Open Shortest Path First (OSPF) is a link-state routing protocol for Internet Protocol (IP) networks. It uses the shortest path first (SPF) algorithm to calculate the best next hop for each packet, and it supports equal-cost multipath routing. OSPF is a classless routing protocol, which means it can carry traffic … Read more
What is Area Border Router? An Area Border Router (ABR) is a type of router that connects different areas, or networks, within an Autonomous System (AS). An AS is a group of networks under the same administrative control. When an AS contains multiple areas, it is said to be a multi-area network. Area Border Routers … Read more
It is a Link State Protocol which protocol working on links call link-state protocol & Router adds link information to the Database. In Distance Vector Protocol we know about only neighbours but in Link State behaviour everyone makes their own database and shares it with all Routers. OSPF states of the open shortest path first … Read more
