ARP table refresh

RouterOS General
1

Hi.

I have hosts on internal subnet that frequently switch IP address between 2 servers and therefore MAC address of that IP change.

When MAC address changes, even after 5 minutes Mikrotik router still has old MAC address in it’s ARP table. And if I ping IP address from Mikrotik router, it still keeps the old MAC address.

Is there a way to set up Mikrotik so that MAC address is renewed more frequently, for example, 1 minute or even less?


Mikrotik version 2.9.6

Set the MAC address of the IP that moves to ff:ff:ff:ff:ff:ff (Always broadcast I believe). That normally solved these types of issues for me on multiple instances with multiple OSes.
