OSPF v2 (IPv4)

Open Shortest Path First (OSPF) is an Interior Gateway Protocol (IGP) used to exchange routing information between routers within a single autonomous system (AS).

OSPF calculates the best path based on true costs using a metric assigned by a network administrator.

RIP, the oldest IGP protocol chooses the least-cost path based on hop count.

OSPF is more efficient than RIP, has a quicker convergence, and provides equal-cost multipath routing where packets to a single destination can be sent using more than one interface.

OSPF is suitable for complex networks with a large number of routers. It can coexist with RIP on a network.

You can run OSPF over a route-based VPN by enabling OSPF on a virtual tunnel interface (VTI).

Gaia Embedded supports OSPFv2, which supports IPv4 addressing.

Note - Starting from R81.10.05, in a cluster environment, configure the routing settings on the Active member. These settings are automatically synchronized to the Standby member. In earlier versions, you must configure the routing settings separately on each Quantum Spark Cluster Member.
