You can also catch and minimize mistakes in real-time by:

1) Implementing and enforcing a proper change control system

2) Implementing tools like Rancid, which are designed to scrape router
configs and E-Mail changes in the format of a unified diff to everyone
in your engineering team.

3) Make liberal use of tools like RtConfig so routine changes aren't a
painful (read: manual) time-consuming process.
