Hi, Xu Yang and Kevin Scaggs ,
Could you help clarify one questions? In the L2ProtocolData information element in this model, I think few attributes (segmentationId, physicalNetwork, and routerExternal) are related to align with Openstack provider network supporting'' in the future, right? also, for these attributes Stereotypes marked as 'Futrure'. So, is there any plan to support it? Do you know some use cases for them?
BestRegards
Fei
Xu Yang
Hi Fei,
Yes, those attributes are for supporting the provider network concept. The stereotype is "Future", as the team hasn't agreed on accepting these changes. There's a discussion in ETSI NFV as well, though no conclusions has been reached. For the use case, I guess VoLTE is using it.

Hi Xu Yang,
I was looking on where onap is supporting or not the provider network concept. Do you know if the attributes from L2ProtocolData (segmentationId, physicalNetwork, and routerExternal) are supported in latest release. If not, there is any prevision for that?
Thanks & BestRegards
Fei Zhang
