 The OSPF (Open Shortest Path First) protocol is a link-state routing protocol class. For IPV4 OSPF Current version number OSPFV2, the version number of John Moy is introduced in RFC 1247 and is updated in RFC 2328. In 1999, the OSPFv3 for IPv6 was published in RFC 2740OSPF features SOSPF does not use transport layer protocols. The reason is that OSPF packets a
