ACI and Open Stack plugin questions

[chaejungho]

When i plugin ACI and Openstack, have confirmed that there is "GBP, ML2 Driver".

What is the difference between "Group-Based Policy and APIC ML2 Driver"?

What does "OpFlex" mean when I mention "Deploying OpFlex ML2 and GBP" in the manual?

What areas of the "Cisco APIC" can you participate in from the open stack?

I do not understand the manual well.

Please explain in detail.

Openstack is used as an orchestrator for ACI via API calls. It can provision configuration included EPG/BD/VRF and contracts. ACI supports integration with the Openstack networking component, Neutron. 

An Openstack environment can integrate with ACI with 2 flavors: Group-Based Policy or ML2.

Openstack's Open vswitch (OVS) would be used as a network agent. ACI can build an Opflex tunnel and provision flows on the OVS.

If I'm integrating ACI with Openstack which method I should choose ML2 or GBP. Which one is best.

What is the basic difference between them and how it much difference can come in implementing it.

Which one is simpler to implement,
