I added the summary-address command to the config and this is not working
inside a single area. Check out my config below:

Josh,
Between areas you would use the area # range command to summarize routes
learned from an external route source. To summarize a group of contiguous
networks within an area, you use the summary-address command under ospf.
This command allows you to summarize several networks into one advertisment.
I hope this helps.
