Open Shortest Path First(OSPF)

Jun 27, 2010 at 8:51 pm in Protocol by Madhan · 1 Comment »

OSPF is an open-standard, classless routing protocol that converges quickly and uses bandwidth as a metric. OSPF is a link-state routing protocol and uses Dijkstra’s Shortest Path First (SPF) algorithm to determine its best path to each network. The OSPF protocol performs the two basic primary functions:

  • Path Selection and
  • Path Switching.

OSPF Network Structure

OSPF routing domains are broken up into areas. An OSPF network must contain an area 0, and may contain other areas. The SPF algorithm runs within an area,  [read more →]
