Overview
Open Shortest Path First (OSPF) is a link state interior gateway protocol developed by the OSPF working
group of the Internet Engineering Task Force (IETF). At present, OSPF version 2 (RFC 2328) is used.
NOTE:
Unless otherwise noted, OSPF refers to OSPFv2 throughout this chapter.
OSPF has the following features:
• Wide scope—Supports networks of various sizes and up to several hundred routers in an OSPF
routing domain.
• Fast convergence—Transmits updates instantly after network topology changes for routing
information synchronization in the AS.
• Loop-free—Computes routes with the shortest path first (SPF) algorithm according to collected link
states, so no route loops are generated.
• Area partition—Allows an AS to be split into different areas for ease of management and routing
information transmitted between areas is summarized to reduce network bandwidth consumption.
• Equal-cost multi-route—Supports multiple equal-cost routes to a destination.
• Routing hierarchy—Supports a four-level routing hierarchy that prioritizes routes into intra-area,
inter-area, external Type-1, and external Type-2 routes.
• Authentication—Supports interface-based packet authentication to ensure the security of packet
exchange.
• Multicast—Supports multicasting protocol packets on some types of links.

Configuration prerequisites
Before configuring OSPF, you must configure the link layer protocol, and IP addresses for interfaces,
making neighboring nodes accessible with each other at the network layer.
