I include in that discussion also Ted and Deng who were also working on L2RA at that time, I see that draft-lemon-dhcpv4-relay-encapsulation is the normative part of L2RA.

Hi Pavan, Bharat,
May you try and help understanding why the draft has been abandoned?
I searched the email thread but found no information.
It may be important when proposing to resume the argument.

Thanks,
Claudio

Subject: Re: [dhcwg] L2RA

Hi Claudio,
Indeed, it has been a while that we worked on L2RA and we moved on to different domains. I am adding Bharat’s email. I don’t remember exactly when and how we stopped working on this.

I am certainly interested in revisiting the old draft with ORAN based transport context. The old draft is very DSL specific but the majority of the content remains relevant

Thanks,
Pavan

Hi Bernie and Timothy,
We have recently found a new scenario driven by O-RAN and CPRI specifications where a L2 ethernet switch needs a L2 Relay Agent with DHCPv4.
There’s no IETF definition of that scenario, but a draft exists https://datatracker.ietf.org/doc/html/draft-ietf-dhc-l2ra-06 expired 11 years ago that was aimed at describing L2RA.
The existing rfc6221 has a reference to the L2RA work and even Broadband Forum’s TR-101 complains that a L2RA didn’t exist.
Do you think that is possible to resume that draft and proceed forwards, or even include the L2RA specific parts in a new revision of rfc3046?

Thanks and best regards,
Claudio Porfiri
