i am a networking teacher in iti enrico fermi modena, an high school (students from 16 to 19)
at school we have about 60 mikrotik hap ac lite and with our students test successfully vlans from 2018.
during lockdown we work with students at home with chr and virtualbox using internal networks to connect 2 chr with the same vlans confs as hap hw devices but only 2 test on about 60 were successful and the others do not run as espected (do not ping at all).
more and more attempts to understand why but now we only have this RUNNING conf on alice and bob chr devices on virtualbox:
# sep/07/2020 14:59:38 by RouterOS 6.45.8
# software id =
add name=aliceBr vlan-filtering=yes
set [ find default-name=ether4 ] advertise=\
/interface wireless security-profiles
set [ find default=yes ] supplicant-identity=MikroTik
/interface bridge port
add bridge=aliceBr interface=ether4
add bridge=aliceBr interface=ether2 pvid=20
add bridge=aliceBr interface=ether3 pvid=30
/interface bridge vlan
add bridge=aliceBr tagged=ether4 untagged=ether2 vlan-ids=20
add bridge=aliceBr tagged=ether4 untagged=ether3 vlan-ids=30
add dhcp-options=hostname,clientid disabled=no interface=ether1
add distance=1 gateway=192.168.11.1
but we cannot restore this running confs on some other couple of chr with more different chr version and from export files or backup files.
can you help us ?
thanks marco mescoli
