Hi Zahed, FWIW, a new version that resolves your DISCUSS is available online: https://www.ietf.org/rfcdiff?url2=draft-ietf-opsawg-vpn-common-11.

I added this NEW text: > > Some transport protocols use existing protocols (e.g., TCP or > UDP) as substrate. The match criteria for such protocols may > rely upon the 'protocol' under 'l3', TCP/UDP match criteria > shown in Figure 4, part of the TCP/UDP payload, or a > combination thereof. This version of the module does not > support such advanced match criteria. Future revisions of the > module may consider adding match criteria based on the > transport protocol payload (e.g., by means of a bitmask match). > > Do we need to say more?
