For Juniper at least, you can use "commit scripts" to enforce these
rules in real time each time a configuration commit is performed--if
the candidiate configuration change doesn't follow the rules, the
commit fails (or the configuration can be changed automatically to do
something).  For example "all interfaces must have a description on
them", or "changes to MSTI configuration are not allowed".
