I guess what I could do was to "poison" their arp cache for each

The kernel should send out gratuitous ARP requests whenever you assign
an address to an interface. You could confirm that this is happening
by tcpdumping the interface whilst you add aliases.
Rummaging around in ports, you might find net/arping or net/p5-Net-ARP
useful if you want to manually generate gratuitous ARP requests.
I have bad news for you all: this doesn't seem to happen for alias
interfaces.
I've just tried to replicate what happened days ago. I've verified that
only the
base (non alias) interface sends proper is-at messages. The aliases
don't....
I could't either ping from one of those addresses or ping to one of them
until
I isssued:
arping -S aliased-address router-address
The router didn't know the mac addresses had changed until then...
Can anyone confirm this?
