Strange Issue with 802.1Q on new cluster

Jan 16, 2022
hello everyone i have built a identical cluster that is not able to get traffic 802.1q to pass correctly

for example i have a Mikrotik VM that see the neighbors on the coresponding QINQ Zone but cannot access to them.

Firewall are off , both cluster end in the same HPE Stack . the original cluster as not issue at all.

the MTU are identicals as well.

i deleted all zones and restarted with no result. even the Cross communication between nodes is not working .

i never seen someting similar before and im out of ideas... i am running last V7 version with ifupdown2 SDN to last version.

both cluster use linux bridge with vlan aware = yes .

Strange thing i noticied . If i change on that cluster to 802.1AD , i am getting a IP from the correct vlan.

but the entire cluster stop processing Data on the vmbr1 bridge for some reason.

as soon as i put the SDN zone to 802.1ad , i have no more data flowing on the other virtual machines using vmbr1
