Jitsi Meet setup to scale single meeting over multiple videobridges

Hi all,
looks like I need some help.
I want to create a setup which allows multiple videodriges to be used for the same meeting. I understood that OCTO is used that. But I’m not able to find recent documentation for that.

The setup from the link above is working for me. But I understood that this is not solving the resource issue for bigger conferences.

I guess it is related to this:

Existing bridge does not have a relay, will not consider other bridges

Beside that basic setup I have added into the sip-communicator.properties of the JVBs:
org.jitsi.videobridge.REGION=vbr
Means vbr1 and vbr2.

More less what is written here: This is tutorial to configure octo feature on jitsi. · GitHub

Would be great if I could get some pointers to look into.

Best regards
Christoph

Hi all,
I guess I manage to find the missing bit in my setup:

Currently it is looking quite promising.
