OSPF is the most widely used IGP. When we discuss IGPs, we’re talking about one routing domain, or Autonomous System (AS). Imagine a medium-sized company with multiple buildings and departments, all connected and sharing two redundant Internet links.

OSPF is a dynamic routing protocol. It quickly detects topological changes in the AS (such as router interface failures) and calculates new loop-free routes after a period of convergence. This period of convergence is short and involves a minimum of routing traffic.

Open Shortest Path First (OSPF) is a recent entry into the Internet interior routing scene. OSPF Version 2 is documented in RFC 1583 (a lengthy document that I find very difficult to read). Sanctioned by the IETF, it is intended to become Internet's preferred interior routing protocol.

Version. 8 bits. OSPF version number. ... Type. 8 bits. OSPF request/reply code. ... Area ID. 32 bits. The area that this packet belongs to. All OSPF packets are associated with a single area. Most travel a single hop only. Packets travelling over a virtual link are labelled with the backbone Area ID of 0.0.0.0.
