Please note that this document does not conflict with draft-mhkk.
Regarding “Control plane convergence should indeed play a pivotal role”, I
observe that draft-mhkk is still based on the separate N2/N4 signaling in case
of 5G, even though the N4 is translated to BGP.

Here is my summary.
General comments:
1. There were some architecture discussions about SRv6-transporting-GTPu vs

SRv6-replacing-GTPu and the other is out of scope. That's ok - but the draft
should omit "3. Motivation" and

Hi Miya,
As Joel pointed out, it is 3GPP not IETF who may adopt SRv6 as a user plane.
Before then, we have to take GTP-U as granted. Of course, if IETF can reach
consensus on the merit, we could recommend to 3GPP and they can decide whether
