VLAN issue with Bridge

Hi,

i will explain you my issus that i have.
I have a Mikrotik 2011L-IN
My config are
3 DHCP Server
1)192.168.88.0/24
2)10.20.20.0/24
3)172.16.16.0/24

So this are all Working on the different Ports and Bridge
Bridge
1)Bridge-local
2)bridge1
3)bridge2

Vlan
1-Vlanid=7 ->bridge-local
2-Vlanid=8 ->bridge-local

3-Vlanid=10 ->bridge1
4-Vlanid=20 ->bridge1

5-Vlanid=900 ->bridge2
6-vlanid=901 ->bridge2

So now i have one Port allocated to a Bridge and Vlan

This was the idea
bridge-local
–ether6
–vlan10
–vlan900

bridge1
–ether2
–vlan7
–vlan901

bridge2
–ether5
–vlan8
–vlan20

But i can just do this (abouve) and when i change anything she reboot directly i think i have a loop on my config but i don’t know how can i do this

bridge-local
–ether6

bridge1
–ether2
–vlan7

bridge2
–ether5
–vlan8
–vlan20

If you need mor information please let me know i can privide the output form Terminal if needed

Best Regards

Please provide the following output:

/interface export compact
/ip address export compact


Maybe more later, but this should get us going.
