ospf routing protocol
Jun 01, 2006 · Related Articles. OSPF is a link-state routing protocol, as we’ve said. Think of this as a distributed map of the network. To get this information distributed, OSPF does three things. First, when a router running OSPF comes up it will send hello packets to discover its neighbors and elect a …
The Open Shortest Path First (OSPF) is a routing protocol for wide area networks and enterprise network. OSPF is perhaps the most widely used interior gateway protocol (IGP) in large enterprise networks. The IS-IS is another link-state dynamic routing protocol, which is more common in large service provider networks.
The Open Shortest Path First (OSPF) protocol, defined in RFC 2328, is an Interior Gateway Protocol used to distribute routing information within a single Autonomous System. This paper examines how OSPF works and how it can be used to design and build today’s large and complicated networks.
Routing Protocol Type:The RIP is a distance vector protocol whereas the OSPF is a link state protocol. A distance vector protocol uses the distance or hop counts to determine the transmission path. A distance vector protocol uses the distance or hop counts to determine the transmission path.
The main difference between OSPF vs BGP is that the OSPF is an intra-domain routing protocol using link state routing, and the routing operation is performed inside an autonomous system while BGP is the inter-domain routing protocol that uses path vector routing, with the routing operations performed between two autonomous systems.
The OSPF (Open Shortest Path First) protocol is one of a family of IP Routing protocols, and is an Interior Gateway Protocol (IGP) for the Internet, used to distribute IP routing information throughout a single Autonomous System (AS) in an IP network. The OSPF protocol is a link-state routing protocol,
The OSPF router protocol is used within larger autonomous system networks in preference to the Routing Information Protocol (RIP), an older routing protocol that is installed in many of today’s corporate networks.
Open-Shortest-Path-First (OSPF) is the most widely used interior gateway protocol routing protocol on the world because it is a public (non-proprietary) routing protocol while its biggest rival, EIGRP, is a Cisco proprietary protocol so other vendors can’t use it (edit: EIGRP has become a public routing protocol since 2013).
