Summary

This appendix discussed the evolution of the OSPF protocol by tracing its path through the RFCs. Each RFC was examined and briefly discussed to include whether it is still relevant in today’s networks. RFC 2328 is the most current OSPF RFC.

Now that you have a complete picture concerning the technical resources and documentation surrounding OSPF, you should familiarize yourself with the functional environment and hierarchy used by OSPF, as discussed in the text.
