Hi All,

Request you all to provide inputs of the below queries:

As per my understanding GBP constructs are mapped to neutron calls for 
example - creating an endpoint, the neutron mapping driver will map it to 
the existing port creation method. Similarly to achieve the complete 
functionality of GBP openstack, I have checked for the neutron calls and 
it includes network, subnet, port, router, security group.

Creating a contract - policy rules..Will this include a call to firewall 
rules or only security group calls will be done?
I need to integrate Openstack with Opendaylight(ODL). To achieve the 
interface between two will it be done by ML2 plugin and neutron mapping 
driver of Openstack or something additional is required?
The neutron northbound APIs of ODL include network, subnet, port, router, 
security groups, firewall calls. Any other call that needs to be included 
a part from these in ODL.
Do the neutron calls that will be mapped by the neutron mapping driver of 
openstack are something different from the previous neutron calls that 
were being made without using GBP??? For example: The network create call 
that was used previously with ODL without using GBP in openstack. Will it 
be different from the network call to ODL that will be made by GBP mapping 
driver of openstack.
How the GBP project in openstack will be affecting the Opendaylight 
neutron calls??



Thanks in Advance
Sachi Gupta

Thanks for your interest in GBP, responses inline.

The code has been in review in gerrit for a while now, you can find
all the links to all the patches here:
https://wiki.openstack.org/wiki/Meetings/Neutron_Group_Policy/Patches
We are also consolidating this code in Stackforge so that its usable
starting  from the Juno release.

The wiki page above has links to client, Horizon and Heat patches.

I know that this was planned, so you would probably need to check with
the author of the following patch for the status on this:
https://review.openstack.org/#/c/105606/
We can also bring this up for discussion during the weekly IRC:
