Dear authors,

I have performed review of draft-ietf-nvo3-evpn-applicability<mailto:draft-ietf-nvo3-evpn-applicability@ietf.org>. Even though I have few comments he draft is in good shape. Kindly address these comments and publish a new version of the draft. Will be doing the shepherd write up after that.

Comments:

·         Please fix the type for WMware to VMware

[JORGE] Fixed, thx.



·         Sec 1. Introduction -  I see EVPN control protocol is going to reside on NVEs only. Are there alternate mechanisms like controller? If so, would it be good to mention how it is going to be used in those scenarios? If out of scope and covered elsewhere, please do mention that.

[JORGE] We clarified that, as specified in [RFC7365] NVAs could be used, in which case, EVPN may still be used to convey information among NVAs.



·         Sec 2. EVPN VLAN-aware bundle service model: Is there a reference to “Ethernet Tag”? If so, kindly add it.

[JORGE] done, thx



·         Sec 4.2 - TS2 and TS3 are also virtual machines correct? Could you explicitly mention that?

[JORGE] added this:

“TS2 and TS3 are physically dual-connected to NVEs, hence they are normally not considered virtual machines.”





·         How is the control plane traffic is secured, for mechanisms described in 4.2.1, 4.2.2 and 4.2.3. Sec 4.6 describe advertising security capabilities via CP, but doesn’t describe about how control plane protocol could be secured. If they are covered elsewhere, please add references as part of security section.

[JORGE] added some information in the security section.


thanks
