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

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!
