Linda’s started out in IDR as a replacement of IP-Sec tunnels for Tunnel encapsulation.   The Application draft for SDWAN is in BESS.  


Due to the shorten meeting time, I recommended to Linda and her co-authors to only do the mechanism presentation in either BESS or IDR.   I recommended if she presented mechanisms in IDR that she shorten her time slot in BESS to 2 slides and 5 minutes.   Or if she presents the mechanisms in BESS (15 minutes) we do not need to present in IDR.  


Hu Jun, Linda,  and Ali S. all proposed mechanisms as a replacement for 3 IP-Sec tunnel-types being removed by draft-ietf-idr-tunnel-encaps-20.txt.   Each of these 3 solutions proposed either a replacement for IP-SEC or a new tunnel type (EVPN from Ali).   As a replacement for the tunnels in IDR,  Jun and Linda’s draft could go in either WG.   The EVPN draft from Ali clearly belongs in the BESS WG.  I am convinced by the authors we have 3 different use cases.  


As part of a joint work between IDR and BESS, all 3 gave presentations in IETF 105 and received feedback on security issues.  I chaired this section joint section.  I have seen security corrections and packing improvements from Jun Hu draft and Linda’s draft.  I have not seen any textual security improvements in the EVPN text.  Ali has reported security improvements, but the text and the text of drafts it points to does not seem to matter.   I hope to see that we can use common sub-TLVs for 3 different tunnel types. 


The drafts for the new tunnel types will need to be review and vetted by both working groups (IDR and BESS). 


I hope if Ali presents on the -03.txt he will provide details on why he has not address the concerns from the security review in IETF 105 and what alignment he plans with draft-ietf-idr-tunnel-encaps-20.txt. 


Cheers, Sue

Hi Linda, et al, +BESS, 

Isn’t this draft under the auspices of the BESS charter?

Jimmy and IDR chairs, 


Can you add the following to the agenda?


The document describes encoding of BGP UPDATE messages for the SDWAN edge node discovery.


Thank you very much.  I am very sorry that I missed sending the email (I thought I did).
