A Brief Explanation of OSPF with Cisco Equipment

OSPF (open shortest path first) is the preferred IGP (interior gateway protocol) today. The OSPF protocol is an algorithm that finds the shortest available path in a network environment to route traffic through. Various network equipment manufacturers support OSPF including Cisco.

Cisco networking equipment adheres to the OSPF V2 protocol. More information about that version of OSPF can be found on the internet under RFC 2328. Cisco chose to use this version of the OSPF protocol because of certain key features:

  • Stub areas

  • Route redistribution

  • Authentication

  • Routing interface parameters

  • Virtual links

  • NSSA

  • OSPF over demand circuit

Cisco networking equipment allows network admins the choice of the type of OSPF network they want to implement. Networks can be configured as either broadcast or NBMA types regardless of the default media.

Though the OSPF protocol can be configured with all default settings without further configurations, Cisco's iOS can be used to configure the protocol for a variety of different use-cases. Read the documentation for an in-depth explanation of the configuration options available for the OSPF protocol with Cisco's equipment in the Cisco knowledge base. Configuration changes may need to be made for OSPF to work across multiple hardware vendor devices.
