CCNA Training-OSPF Routing Protocol
September 9th, 2010
One of the most popular dynamic routing protocols available is the Open Shortest Path First (OSPF). This is a link-state algorithm protocol (compared with distance-vector protocols like RIP) and is categorized as an Interior Gateway Protocol (IGP). IGP protocols are running within the same Autonomous System network (i.e a network under the same administration domain, such as a company’s LAN network, a university’s campus network, a corporation’s private WAN network etc).
The strength of the OSPF is that it is a hierarchical protocol using network areas. Routing information distribution becomes more structured and also simpler to troubleshoot.
OSPF is extensively used in Cisco networks and is fully supported by the Cisco IOS operating system. However, OSPF is also fully supported by other networking vendors such as Juniper etc.
The first step done by the OSPF is to establish communications with the neighboring routers.
