Having many routers exchange the link state database could flood the network and reduce its efficiency — this was the need that led to the creation of concept Areas. Figure 1. All routers within the same Area have the same topology table - Link State Database - but different routing table as OSPF calculates different best paths for each router depending on its location within the network topology while they will all share the same Link State topology.
The goal of having an Area is to localize the network as follow:. With Area boundaries , updates are kept only inside the same area , while other areas remain completely unaware of the update. OSPF routers generate packets of information that are exchaged with neighboring routers. These packets are designed for several purposes such as forming neighbor relations between routers, calculating cost and best path for a specific route and more.
Link State Advertisement LSA : The primary mean of communication between OSPF routers, it's the packet that carries all fundamental information about the topology and is flooded between areas to perform different functions, there are 11 types of LSA packets that will be covred in great depth in future OSPF articles here on Firewall.
Working inside of an Area is hierarchically organized among routers that share this area and are categorized as:. ABR Routers are responsible for summarizing IP addresses of each area and suppressing updates among areas to prevent fault containment. The DR sends updates to all Area routers using the Multicast address Deal with bandwidth spikes Free Download. Web Vulnerability Scanner Free Download.
OSPF uses multicast address Note — Both the routers neighbors should have some type of authentication enabled. Writing code in comment? Please use ide. Skip to content. Change Language.
