Hello,

Also, if you are used to reading scientific papers, the following URL will lead you to an article from Dr. Garcia who authored the DUAL algorithm.

The diffusing computations themselves have been coined by Dr. Dijkstra and Scholten and the paper discussing them can be found here:

http://www.cs.utexas.edu/users/EWD/ewd06xx/EWD687a.PDF

Both these documents are solid mathematical papers that discuss the underlying principles upon which the EIGRP is built.

Best regards,

Peter
