Limit IP per MAC address

Hello!
I use vyos for IPv6, some time client add many IPv6, so I want limit limited number of IP per MAC address, Does vyos have any configuration that supports it?

Hello @dzung042
I think it is possible to do this, but how do clients add ipv6?

my client sometime add by script 1000ip, so I want limit 50 IP per MAC address.

In this case, it is possible to use only the system limit, there is no such possibility on the specific interface, it is the limit of the linux system, as an example:
