Testing router code before deployment

[Tom Holbrook]

Just curious what testing protocol people use with router code (IOS or JunOS for example) when considering deployment of a new version. Obviously the deployment would be made incrementally, but I wonder if you do anything more than running it in a lab router for a couple of weeks before the initial deployment.

Thanks
-Tom
