3.5.5 OSPF protocol
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 (RFC2328) is used.
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 multipleequal-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.
