Permanent ARP entry failed

This has happened twice now and I'd really like to know why and how to prevent it.



In our OpenWRT router, I add a permanent ARP entry on startup like so:
ip neigh add 192.168.0.254 lladdr ff:ff:ff:ff:ff:ff nud permanent dev br-lan



This works fine, but after some time (months), the entry becomes FAILED. If I now do ip neigh, the entry looks like this: 192.168.0.254 dev br-lan FAILED



It was my understanding that this shouldn't happen to permanent entries, but it somehow does. Why is this happening and how can I prevent it?
