Hello,
does anyone know if Juniper MX does opportunistic ARP? Meaning, will
it send out an ARP request by itself when an ARP entry expires (like
Cisco does) or will it wait until it needs to resolve the ARP entry
when a packet arrives?
Regards
Sebastian

Yes, juniper will re-arp after aging timer expires, default is 20 minutes.
Juniper usually adds a jitter so that ARP does not expire en masse.
If the ARP reply is not received, packets will be dropped unless the
corresponding reply to who-has comes back
Hope this helps
