WiFi mesh : broadcast & multicast policy

[Ankit53]

Hi,

What is broadcast and multicast policy in N layer WiFI mesh network?
If Root is broadcasting frame , dose it reach to end nodes of network or just received by the ones who are in direct connection range of root?

Thank You,

I think the answer to your question is in the data transmission of the mesh docs here

Thank You Lee!

is this broad cast ans multicast policy are cloned from WiFi specification or ESP has defined their own for ESP-mesh only?

Is Multicast-Group Address (01:00:5E:xx:xx:xx) customized feature of ESP32 mesh or in WiFi specification described somewhere? I could not find same in specification so.

Hi Ankit,
In my mind, the policy in document is for ESP_MESH only. It only works in mesh layer，although the Multicast-Group Address is same as WiFi specification.
