I am using RB1100AH2 with OS 6.10 and CRS125-24G OS 6.9
I notice on my two routers that when a device reboots or changes ip due to DHCP lease expiration the ARP list shows the MAC assigned to two different IPS (old and new).
The ARP list is not automatically updated. The device is not removing the old ARP entry automatically. This is causing lots of problems for me.
I have ARP set to enabled on all the interfaces.
