Почему образуется петля на linux bridge?

Question

[Bermut]

Хочу организвать мини-маршрутизатор на debian 12, требуется создать мост с 50 vlan, создал скрипт -

скрипт

vlanidstart=900
vlanidend=950
vlan=$vlanidstart
ip l s up ens18
brctl addbr br-servers
brctl stp br-servers on
addvlans () {
        if ! [[ $vlan > $vlanidend ]]; then
                ip l a l ens18 name ens18.$vlan type vlan id $vlan
                ip l s ens18.$vlan master br-servers
                ip l s up ens18.$vlan
                vlan=$((vlan+1))
                addvlans
        fi
}
addvlans

При поднятии этого моста он уходит в петлю, при этом корреляции между состояниями stp не заметил, в dmesg такие сообщения -

Как правильно создать мост без сетевой петли?

Должен отметить, все это делалось в виртуалке на pve, интерфейс ens18 - находиться так же в бридже с физическим интерфейсом на самом хосте

Answer 1

[Bermut]

Как подсказали на lor, требовалось включить vlan-filter на мосту, командой ip l s br-servers type bridge vlan_filtering 1
Так же в моем случае еще помогло отключение stp на мосту.
