Automation

  The scenario is that there are two M class routers in different data centers, very large portions of the configuration on these routers should be identical ( for example everything under the 'services' hierarchy).  Is there a standard method to automatically (or through a command/script) ensure that updates to certain portions of the config on one router are mirrored on the other?

Take a look at the share-data.slax script in Junoscriptorium. It might be what you are looking for:

Thanks, this definitely apepars to be what I'm looking for.
