Hey There!
Im new in this forum,I would like to share my "issue" on my home mikrotik routerOS v7.14.1 (hAP ax2).
After reboot on interfaces appear a loopback interface with lo name,and when i remove it manualy it appears again on next start automaticaly.
Well- it hasn't giving me any trouble/issue of working out the connection etc. but seems like it looking annoying and it loks weird since it appear again even if I remove it manualy.
Maybe someone has this "technical issue too" or intuite is leading me something is missing from routerOS.
my bridge conf as below:

0 R ;;; TRUNK-20,200
name="BR_LAN" mtu=auto actual-mtu=1500 l2mtu=1568 arp=enabled arp-timeout=auto mac-address=4C:XX:8A:XX:XX:DC

1 R name="BR_VLAN200" mtu=auto actual-mtu=1500 l2mtu=1564 arp=enabled arp-timeout=auto mac-address=4C:XX:8A:XX:XX:DX

Thanks in ADVANCE!

Standard loopback interface.
It has always been there but was hidden in the past.

Recent versions of ROS made it visible.

Don't worry too much about it and just let it be

you're not the first one to complain about this recently exposed loopback Interface. Accept it. It does no harm. If people would care as much about their bloated config...

some kind of loopback-o-phobia

Can you create a second proper "type=loopback" interface or do you need to still do it the old school way of creating a bridge interface with no ports?
