3.10.6 OSPF
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).
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.
