While studying VLAN aware mode

It mentioned

"You can configure both VLAN-aware and traditional mode bridges on the same network in Cumulus Linux; however you should not have more than one VLAN-aware bridge on a given switch"

So I would like to check even latest version of Cumulus 3.2.x is still same?

If yes, If my design have multi bridge in single switch.  Only one VLAN-aware is allowed and others I need to setup using traditional mode bridge?

Yes currently only one VLAN aware bridge can be configured. Can you explain your use case for multiple bridges?

Simply draw a network diagram and post here.

All running L2 environment.

Leaf1 and Leaf2 is a pair of MLAG1
Leaf3 and Leaf4 is a pair of MLAG2
Leaf5 and Leaf6 is a pair of MLAG3

Please take care those VLAN allow passing thru between MLAG1 - MLAG2 is different to MLAG2 - MLAG3

Let's concentrate at Leaf3 config.   Simply edit the important part I think

auto bridge01
iface bridge01
    alias Bridge between MLAG1
    bridge-ports peerlink server3 server4
    bridge-pvid 1
    bridge-vids 10 20 30 40
    bridge-vlan-aware yes
    mstpctl-treeprio 32768
auto server3
iface server3
    bond-salves swp21
    clag-id 1000
    bridge-vids 10 30
auto server4
iface server4
    bond-salves swp22
    clag-id    1001
    bridge-vids 20 60
auto peerlink
iface peerlink
    bond-slaves    swp31 swp32
auto peerlink.4090
iface peerlink.4090

auto bridge02
iface bridge02
    alias Bridge between MLAG3
    ***** how to config? *****

I put 'bridge-vlan-aware yes'   which it used connect to MLAG1.   

But now I am no idea between MLAG2 - MLAG3 bridge how to setup.
