The link-state advertisement (LSA) is a basic communication means of the OSPF routing protocol for the Internet Protocol (IP). It communicates the router's local routing topology to all other local routers in the same OSPF area. OSPF is designed for scalability, so some LSAs are not flooded out on all interfaces, but only on those that belong to the appropriate area OSPF network type NBMA (Non-Broadcast Multiple Access) uses only unicast communications, so it is the preferred way of OSPF configuration in situations where multicast addressing is not possible or desirable for some reasons. Examples of such situations This page was last changed on 12 November 2012, at 05:11. Text is available under the Creative Commons Attribution/Share-Alike License and the GFDL; additional terms.

OSPF was designed expressly for IP networks and it supports IP subnetting and tagging of externally derived routing information. OSPF also allows packet authentication and uses IP multicast when sending and receiving packets. Cisco supports RFC 1253, OSPF Version 2 Management Information Base, August 1991. The OSPF MIB defines an IP routing. A number of different Cisco IOS OSPF configuration commands are available, but at its most basic, OSPF configuration uses three commands: the router ospf, network, and router-id commands. The router ospf process-id command is the beginning of any Cisco IOS OSPF configuration. It is used to create or modify an existing OSPF routing process and. Open Shortest Path First. Wikipedia . Proper noun . OSPF. Initialism of open shortest path first: a link-state routing algorithm that is used to calculate routes based on the number of routers, transmission speed, delays and route cost. Anagrams OSPF version 2, on the other hand, was designed for IPv4. IS-IS is neutral regarding the type of network addresses for which it can route. This allowed IS-IS to be easily used to support IPv6. To operate with IPv6 networks, the OSPF protocol was rewritten in OSPF v3 (as specified in RFC 2740) OSPF (Open Shortest Path First), a link state routing protocol, is massively adopted in large enterprise networks. OSPF routing protocol collects link state information from routers in the network and determines the routing table information to forward packets. This occurs by creating a topology map for the network

OSPF (Open Shortest Path First) OSPF is a standardized Link-State routing protocol, designed to scale efficiently to support larger networks. OSPF adheres to the following Link State characteristics: • OSPF employs a hierarchical network design using Areas. • OSPF will form neighbor relationships with adjacent routers in the same Area OSPF is a link state routing protocol which was designed to be scalable.

• OSPF stands for Open Shortest Path First; It is used to dynamically advertise locations of IP networks in your network (AS). Each OSPF router will run a calculation on the distance (aka cost) to each network and pick the shortest cost path. OSPF also allows parts of a network to be grouped together into areas
