OSPF Routing Protocol

This section covers the Open Shortest Path First (OSPF) protocol. We analyse the OSPF protocol, explaining why the OSPF protocol exists, how OSPF works, OSPF concepts, OSPF Areas, OSPF router roles and much more.

Our OSPF section has been designed to cover engineers who are new to OSPF (CCNA level) and progressively covers OSPF CCNP professional level. Our articles include examples of OSPF configuration for Cisco routers, ensuring a complete coverage of the OSPF protocol.

Additional OSPF articles will be progressively added as we continuously expand the OSPF section.
