local-proxy-arp is useful when you have some old IP cameras with broken IP stacks(reolink). On a reboot the cameras work for a few hours/days but will eventually not reply to arp on the same broadcast domain. Setting local-proxy-arp on the router vlan interface for that subnet allows for it to always work.

Since the bootcamp in Riga, I have really understood the functions. 🙂

I got in my mind that way: proxy-arp works not between devices in the same l2-segment, but needs a entry in the routing table to work. local-proxy-arp works like a proxy in the l2-segment. every arp-request is answered by the router (regardless of the routing table entries). the combination with horizon is new to me.

Mikrotik, i still can't understand why do think that arp reply and learning modes shuold be combined in one place ... they must by separate as all big players do. Because there are cases then you don't want to dynamically learn arp, but want to proxy it.

Why is it useful to have network (bridged) members not sharing a broadcast domain?

Прикольно. Выглядит довольно олдскульно, как артефакты ушедшей цивилизации :)
Сейчас стандартный путь - роутинг, маршрутизаторы, BGP и вот это вот всё.
