ADVANTAGES OF USING OSPF AS A FAVOURED ROUTING PROTOCOL.Open Shortest Path First (OSPF) is a relatively new kid to the Internet routing scenario.It is aninterior routing protocol, this protocol employs link state routing. This protocol was developed mainly because there was a need for non-propriety, high functioning Internal Gateway Protocol (IGP) for the TCP/IP family. Since the OSPF was introduced as an open standard. It gave the user unprecedented control over the reaches of a single connected network. The various advantages are summarized here. Compared to RIP, which normally has an upper limit of 15 routers (or 15 hops), the OSPF protocol has no such limitation put over it.

Since OSPF was designed with the aim of handling larger networks, OSPF protocol has the ability to reduce or increase the IP packets being transferred over a time frame.

Since a Shortest Path First (SPF) algorithm is employed, the OSPF protocol provides the fastest address and is loop-free.

OSPF uses aLink State Algorithm, and therefore the OSPF coverage diameter is wider compared to the diameter of the RIP.

The OSPF run network is first broken into 18 pieces or classes.

The main reason behind the OSPF protocol being faster is that whenever changes are made in the routing tables, only the new or updated values are transferred, instead of sending the entire code.
