OSPF(Open Shortest Path First), running within the AS, is a routing protocol based on IP
protocol. It uses the algorithm of SPF (Shortest Path First) to calculate the route metric. It is
suitable for large network and complicated data exchange. Vigor3910 supports up to OSPF
version 2(only for IPv4).
The Autonomous System (AS) used in OSPF can be divided into several areas. Usually, Area 0
will be used as OSPF backbone which distributing the routing information among areas.
When you need faster convergence than distance vector, want to support much larger
networks or want to have less susceptible to bad routing information, you can enable OSPF
feature to fit your request. Note that both routers must support OSPF function at the same
time to build the OSPF connection.
