So yes, to re-iterate, at this point, SPRING and BESS chairs believe this work would be better addressed in the BESS WG.

(Keep in mind we are not proposing any change to data plane MAC learning mechanisms like aging, move, security, etc...) But rather how with the SR encap we will learn the MAC against the source SID under the service SID in the SR encap. NVO3 defining VxLAN, Geneve, etc.. where MAC is learned against Source IP address in the encap didn't go to discuss this in BESS. Are you saying we should discuss the above in the BESS working group? We are not making any relevant changes to the ELAN service, it is true we would need to define a new BGP message to auto-discover the services that will apply to BESS and we will have a draft on that to discuss in BESS.
