I'm not a network engineer, rather a security-focused guy, and I'm also very interested in this topic because the basis for a secure network is a well managed network without any unknown/undocumented assets (network equipment incl. layer 2 as well as network participants). Few months ago I attended a talk of Ivan Pepelnjak, the author of a network engineering blog called ipspace. He talked a lot on network automation and enumerated some success story. I remember he talked about people setting up several data centers in a relatively short amount of time by using a lot of network automation / configuration management.
