Where can I find multi-cluster flat networks support documentation?

Hello!

I'd be happy to test out https://github.com/linkerd/linkerd2/releases/tag/edge-23.8.3 as I have a flat multi-cluster network setup w/ Private GKE clusters.

But I want to make sure I'm setting things up correctly. I tried to look through the edge docs but I didn't find anything regarding the changes.
https://linkerd.io/2-edge/overview/

See: https://linkerd.io/2023/07/20/enterprise-multi-cluster-at-scale-supporting-flat-networks-in-linkerd/ for some background.

#11226

For changes do I need to:

• Add the multicluster.linkerd.io/remote-discovery label to all services that I would like to support with cross cluster communication.
• When linking clusters add --gateway=false to the command

Is this all that needs to be done?

@shadiramadan I believe that's right. The docs are coming in hot and as of this moment are mostly in PR form. See e.g. linkerd/website#1663 for the walkthrough. Let us know how it goes!
