There has been some public available software for backing up Cisco router configuration. The backup is not in CVS but in plain file. Joe --- Alexei Roudnev <alex@relcom.net> wrote:
Hmm, there are many approaches, starting with _what is primary_ (in Moscow's ISP files was primary, in enterprise here configs are primary).
In my case, I use some hard rules: - no matter what is primary, configurations should be stored into CVS or simular system, and made available (for network engineers) on the internal web (with restricted access); - system should collect all changes automatically (or update configs from files automatically), make diffs and send change reports. - In any case, I must be able to see real configuration and see all changes, applying for last few weeks, without telnetting to the box.
Without such things, I am blind ( I feel myself blind, when I come to the new network, and they have not such things in their system, making changes _on live servers_ and making 'telnet' to evaluate configuration).
Few tools (opensource and commercial) allows to automate this job.
One more thing. We tried to review _proposed changes_ and _changed applied_. Practice showed, that it is impossible to see errors in proposed updates, even if 3 - 4 engineers review it (not design flaws, but syntac and semantics errors), so we did not got many use from pre-change reviews (except design ones). But we got extremely high profit from post-change reviews (verifying, what really changed on the router / firewall after maintanance window) - it allows to see some unwanted changes and avoid few possible service disruptions.
