Is it possible to do this in junos, cisco have a config "feature" something like arp 10.249.4.1 0100.5e79.0401 ARPA as an example . It doesn't seem as though this is possible in junos from what I have been able to check or try
I just get a cli error. Surely such a simple feature would be available ?
Please try the format shown in above document. If you still get error, please share the device model and Junos version along with snippet of the config that errors out.
