Hi Gyan,

Many thanks for your information!

I found the Group Policy ID explained as below,

   o  Group Policy ID: 16-bit identifier that indicates the Group Policy
      ID being encapsulated by this GBP shim header.  The Default GBP ID
      value is special and indicates that the GBP option was not set.
      Packet filters SHOULD be able to match on the Default GBP ID value
      as a way to match packets that do not have the GBP option set.
      The default Default GBP ID is 0, but MAY be configured to be a
      value other than 0.  The allocation of Group Policy ID values is
      outside the scope of this document.

It seems that we could add this in the gap analysis draft,
https://datatracker.ietf.org/doc/draft-peng-apn-scope-gap-analysis/

Best regards,
Shuping

Shuping

I am not sure if you are referring to VXLAN-GPE vxlan Generic protocol extension which has changes in the vxlan header to support multi protocol encapsulation, OAM and BUM.

https://tools.ietf.org/html/draft-ietf-nvo3-vxlan-gpe-10



   The capabilities of the VXLAN-GPE protocol can be extended by

   defining next protocol "shim" headers that are used to implement new

   data plane functions.  For example, Group-Based Policy (GBP) or In-

   situ Operations, Administration, and Maintenance (IOAM) metadata

   functionalities can be added as specified in

   [I-D.lemon-vxlan-lisp-gpe-gbp<https://tools.ietf.org/html/draft-ietf-nvo3-vxlan-gpe-10#ref-I-D.lemon-vxlan-lisp-gpe-gbp>] and

   [I-D.brockners-ippm-ioam-vxlan-gpe<https://tools.ietf.org/html/draft-ietf-nvo3-vxlan-gpe-10#ref-I-D.brockners-ippm-ioam-vxlan-gpe>].


Kind Regards

Gyan

Dear all,

Anybody knows about using eVXLAN to carry the Group information? What is the scenario? How the group is identified?

Thank you very much!

Best regards,
