Hi Sraheel,

It looks like you are hitting a PR similar to 232061; at the very least, the error message you are getting is severely misleading.

I would contact the JTAC, after making sure you have a big enough CF; for 8.5, it is 512M if I recall correctly.

If this is not a production router and you have a console connection, you may even attempt to use the no-validate knob, but beware: if the newer JUNOS fails to commit the initial configuration due to validation errors, all your interfaces will stay DOWN, and you will need todo this:

- login on the console (you will get a message about configuration not committed)

- enter configuration mode

- Try to commit, check for errors and correct the problematic statements on the fly.

I would never attempt this without being on-site with console and a recovery media (and of course the saved config on my laptop).

I hope this helps,
