Open shortest path first
OSPF routing is a link-state routing protocol that allows sending of link-state advertisements (LSAs) to all other routers within
the same autonomous system (AS) area. Information about attached interfaces, metrics used, and other attributes are included
in OSPF LSAs. OSPF routers accumulate link-state information, and use the shortest path first (SPF) algorithm to calculate the
shortest path to each node.
Autonomous system areas
OSPF operates in a type of hierarchy. The largest entity within the hierarchy is the autonomous system (AS). The AS is a
collection of networks under a common administration that share a common routing strategy. OSPF is an intra-AS, Interior
Gateway Routing Protocol (IGRP) that receives routes from and sends routes to other AS.
You can divide an AS into several areas, which are groups of contiguous networks and attached hosts administratively grouped.
Routers with multiple interfaces can participate in multiple areas. These routers, called area border routers (ABRs), maintain
separate databases for each area. Areas are a logical grouping of OSPF routers that an integer or dotted-decimal number
identifies.
Areas allow you to further organize routers within the AS with one or more areas within the AS. Areas are valuable in that they
allow subnetworks to hide within the AS—minimizing the size of the routing tables on all routers. An area within the AS may not
see the details of another area’s topology. An area number or the router’s IP address identifies AS areas.
