No, I'm sorry, I don't have access currently to any system where I  
could test this. I just looked it up in Juniper docs, wanting to find  
out if there was something functionally equivalent to the IOS command  
I mentioned previously. My apologies, I should have explicitly  
mentioned this before.

Perhaps you or someone else could look into it or try it out, and  
report any success you may have?

Best regards,
