Support multi VLAN aware bridge


Userlevel 1
Hello,

While studying VLAN aware mode

https://docs.cumulusnetworks.com/display/DOCS/VLAN-aware+Bridge+Mode+for+Large-scale+Layer+2+Environ...

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?

Thanks!

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

Hello,

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 server4

clag-id 1001
bridge-vids 20 60

auto peerlink

bond-slaves swp31 swp32

auto peerlink.4090
iface peerlink.4090
****skip***


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.

Thanks!
