<P> Open Shortest Path First ( OSPF ) is a routing protocol for Internet Protocol ( IP ) networks . It uses a link state routing ( LSR ) algorithm and falls into the group of interior gateway protocols ( IGPs ) , operating within a single autonomous system ( AS ) . It is defined as OSPF Version 2 in RFC 2328 ( 1998 ) for IPv4 . The updates for IPv6 are specified as OSPF Version 3 in RFC 5340 ( 2008 ) . OSPF supports the Classless Inter-Domain Routing ( CIDR ) addressing model . </P>
