Since I'm in a chatty mood, I'll give another example.

While both RFC 2328 and Moy's book are written in a very simple engineering
style, there is some reasonably solid theory behind OSPF, which at least
some OSPF specialists don't appear to fully appreciate.  For example, the
topological restrictions on area adjacency are pretty much the weakest
conditions that avoid counting to infinity, and the extreme care given to
the flooding subprotocol indicates a good understanding of the consequences
of desynchronised LSDBs.

I'm deeply convinced that there is no such thing as sound engineering
without a solid theoretical base.
