First, I am not involved in tacker or in networking-sfc, so I can be
Just to be sure by 'multiple VIM' you mean multi domains, multi
systems, multi OpenStack/VNFinfra sites that are all different?
When it comes to VNFFG over multiple VIM, I think a question is: what
networking-sfc driver already support?
Some other questions:
1. In a single VIM situation, does the networking-sfc driver support
(or port chaining) over multiple different IP subnets?
2. Does networking-sfc support both IPv4 and IPv6?
3. What routing/steering protocol (NSH, SRv6) does networking-sfc
4. How healthy (or up to date) is the development of networking-sfc?
I think modifying tacker (or modifying any other VNF Orchestrator that
plugged to an OpenStack VIM with networking-sfc driver installed) alone
enough. Maybe VNFFG over multiple VIM needs an SDN controller, maybe it
new feature in the networking-sfc driver or new features in neutron...

> As far as I know, current single Tacker controller can manage multiple Openstack sites (Multisite VIM), but it can create VNFFG in only singlesite, so it can't create VNFFG across multisite. I think if multisite VNFFG is possible, tacker can have more flexibility in managing VNF and VNFFG.
