Hi Aparna,

Thank you for interesting in Tacker project.

In Rocky release, we are pushing effort to create VNFFGD with NSD. So we
can use NSD to create VNFs and VNFFGs. Tacker uses networking-sfc to create
service chain between VNFs, but there are some limitation, we can not
support creating VLs, VLs must be existed before (currently, only VNF and
VNFFGs - future are supported).

With the guide in VNFFG (https://docs.openstack.org/
tacker/latest/user/vnffg_usage_guide.html), we also have a patch to support
multiple forwarding paths with a VNFFGD. In the Queens release, we
supported updating VNFFG such as updating flow classifiers, changing
forwarding paths.

Hope that information can help you. If you need more information or wanna
contribute, please join channel #tacker on IRC or email to us :).

Best regards,
Phuoc Hoang Cong
