OSPF(Open Shortest Path First) Overview OSPF(Open Shortest Path First) Overview Link-State Routing Protocol Link-State Database Table(LSDB)을 이용해 전체 Topology를 계산하여 직접 경로 계산이 가능함 - Distance Vector Routing Protocol은 전체 Topology를 계산하지 못하므로 직접 경로 계산이 불가능함 - Distance Vector Routing Protocol은 Neighbor에게 받은 정보로만 경로 계산함 IP Packet에서 Protocol 번호 89번을 사용 - TCP/UDP가 아닌 IP 데이터그램에 의해 운반됨 - OSPF 업데이트는 RIP와 달리 Transport Layer Protocol을 사용하지 않음 - OSPF는 IP Packet으로 Encap됨 Passive-interface 지원 - OSPF Packet을 송신...
