Gyan,

RFC 8365 uses the Encapsulation extended community rather than the attribute, and the extended community was included in the subject draft.  Please see:  https://datatracker.ietf.org/doc/html/draft-ietf-idr-tunnel-encaps-15#section-4.1.

Yours Irrespectively,

John

[External Email. Be cautious of content]


Hi Keyur and other others of this draft.

For vxlan evpn NVO3 RFC 8365 describes the vxlan BGP EVPN overlay architecture and the various encapsulation types below that exist today and have been implemented now by most vendors.

https://tools.ietf.org/html/rfc8365<https://urldefense.com/v3/__https:/tools.ietf.org/html/rfc8365__;!!NEt6yMaO-gk!UooxTZahHMICVYaZqcK72zbOvJNgXz33ZkC1mYjMqeTLuX7IcixCgnvBeqHrO0Q$>


Value    Name

   -----    ------------------------

   8        VXLAN Encapsulation

   9        NVGRE Encapsulation

   10       MPLS Encapsulation

   11       MPLS in GRE Encapsulation

   12       VXLAN GPE Encapsulation

So RFC 8365  has been implemented and it works without this drafts tunnel encapsulation attribute new SAFI defined.

So would this draft once it gets WG adoption update RFC 8365 and any other encapsulation types that work today without this encapsulation attribute.  Would that require vendor to update their code to now support this SAFI.

Since RFC 8365 NVO3 vxlan evpn works well today without this tunnel attributes, please specify what is gained by having vendors update their code to support this new tunnel attribute.

Please help shed some light on this topic.

Kind regards

Gyan

Please be consistent with the terminology.  It is ok to introduce new
terminology, if needed, but please explain that as well.

RFC 3032 is careful in defining what "top" and "bottom" mean for labels of course. Don't you think the meanings of "topmost" and "bottommost" are obvious in that context?
