open shortest path first การใช้

• For routing IP multicast traffic, OSPF supports the Multicast Open Shortest Path First ( MOSPF ) protocol.
• OpenOSPFD, developed by Esben N鴕by, is a companion daemon of OpenBGPD that implements the Open Shortest Path First protocol.
• The NTDR routers also use a variant of Open Shortest Path First ( OSPF ) that is called Radio-OSPF ( ROSPF ).
• This switch was capable of routing, with static routes, Routing Information Protocol ( RIP ), and Open Shortest Path First ( OSPF ).
• Other routing protocols such as Open Shortest Path First ( OSPF ) and Enhanced Interior Gateway Routing Protocol ( EIGRP ) only send updates when a connection changes.
• As a result, the shortest path algorithm is widely used in network routing protocols, most notably IS-IS and Open Shortest Path First ( OSPF ).
• Examples of dynamic-routing protocols and algorithms include Routing Information Protocol ( RIP ), Open Shortest Path First ( OSPF ) and Enhanced Interior Gateway Routing Protocol ( EIGRP ).
• For example, the Open Shortest Path First ( OSPF ) protocol is generally used for routing packets between subnetworks within an enterprise and the Border Gateway Protocol ( BGP ) is used on a global scale.
• Since the advent of IPv6, Open Shortest Path First ( OSPF ) is considered to operate on the link level as well, although the IPv4 version of the protocol was considered at the Internet layer.
• Specific examples of IGPs include Open Shortest Path First ( OSPF ), Routing Information Protocol ( RIP ), Intermediate System to Intermediate System ( IS-IS ) and Enhanced Interior Gateway Routing Protocol ( EIGRP ).
• The communication between peer switches across the IST allows both unicast and multicast routing information to be exchanged allowing protocols such as Open Shortest Path First ( OSPF ) and Protocol Independent Multicast-Sparse Mode ( PIM-SM ) to operate correctly.
• Raw sockets are typically available in network equipment, and used for routing protocols such as the Internet Group Management Protocol ( IGMPv4 ) and Open Shortest Path First ( OSPF ), and in the Internet Control Message Protocol ( ICMP, best known for the ping suboperation ) for example, sends ICMP echo requests and receives ICMP echo replies.
• MPLS Traffic Engineering relies upon the use of TE extensions to Open Shortest Path First ( OSPF ) or Intermediate System To Intermediate System ( IS-IS ) and RSVP . In addition to the constraint of RSVP bandwidth, users can also define their own constraints by specifying link attributes and special requirements for tunnels to route ( or not to route ) over links with certain attributes.
