Regarding RSOO, that’s fine if it doesn’t meet your needs. Just wanted to raise it as it probably isn’t considered as often as it should be.

Hi,

Thank you all for the feedbacks. I will perform the editorial once we have settled the terminology.
Regarding the use of a DHCP Relay, we could of course make a use case of it, but I believe it would go beyond the simplicity of the targeted architecture and I would rather not consider this as RSOO enabled.

Yours,
Daniel

I agree with you completely.
