Here are some handy links that detail OSPF

Most of this material is overkill for the CCNA requirements but I thought that anyone that may be having trouble with OSPF might want to read over the material to get a better understanding of the protocol. I found all of the links helpful.

This is a brief overview of OSPF.

This is the wikipedia entry on OSPF. It details the terms and definitions related to the protocol:

Here are the Cisco white papers on OSPF:

Here is a tutorial on how to build a simple OSPF network environment:

Oh, and for the over achiever, how about a "quick" read of the actual RFC that created OSPF?

http://www.ietf.org/rfc/rfc1247.txt

Sometimes I'm just not satisfied with the limited depth of the CCNA curriculum so I go a little overboard reading up on and studying. Perhaps someone else can benefit from these resources.

Here's another handy one I just found: How to configure OSPF for use over serial links:
