I’ve decided to jump head-first into JUNOS. My short(ish) term goal is to find a position with a service provider. I’ve read that Juniper owns a very significant portion of the SP core, so any exposure to JUNOS can only be a good thing (or so I hope). JUNOS is (obviously) very different from IOS. This is mainly about my experience as an IOS guy starting out with JUNOS.

  • JUNOS is modular, which means more process separation and stability.
  • JUNOS has less versions (no ipbase, advanced enterprise, etc.
  • Commit feature – This allows you to input multiple commands before making them active.
  • Rollback feature – JUNOS saves the last 50 committed configs, allowing you to revert to an old config.
  • Command completion is a little better in JUNOS, you can use spacebar or tab. It will also pick up things that IOS wouldn’t, like user-set variables in the config.
