Gabriel and Rofa, Just to clarify: the purpose of asking you changing from "container.." to "grouping.." is for "i2nsf-nsf-facing-interface-dm" to the "ikev2" and "ietf-ipsec" structure defined in draft-ietf-i2nsf-sdn-ipsec-flow-protection. Not other way around, i.e. not asking draft-ietf-i2nsf-sdn-ipsec-flow-protection to import other properties. By the way, i2nsf-nsf-facing-interface-dm only imported two other data structure "ietf-inet-types" & "ietf-yang-types" besides the "ikev2" and "ietf-ipsec". It has nothing to do with other modules for TTL, SSL, etc. Thanks, Linda On Tue, May 21, 2019 at 3:42 AM Gabriel Lopez <gabilm@um.es> wrote: > Hi Linda, Paul. > > El 20 may 2019, a las 19:52, Linda Dunbar <dunbar.ll@gmail.com> escribió: > > Gabriel, > > Thanks for the explanation. > > Agree with you that *"it does not imply to extend the NSF client > interface to include all the available yang models for every security > service a NSF can support.". * > But a network function that supports I2NSF should be allowed to your IPsec > module, should it? > > > Sure. > > Regards, Gabi. > > P.D.
