[RFE] Using networking-infoblox with opencontrail

[Danil Zhigalin]

Hello,

We are using opencontrail in our infrastructure as Neutron plugin. We would also like to use
networking-infoblox because infoblox is our IPAM and it would be very convenient to have them integrated. First of all we tested networking-infoblox in conjunction with OpenStack mitaka with neutron ML2. It worked fine and then we tried to integrate it in another OpenStack Mitaka that uses Contrail as its core plugin. Unfortunately it didn't work. infoblox-ipam-agent failed to start and spat this stack in log:

as far as I could debug it with pdb, keystone_authtoken is indeed in the cfg.CONF namespace.

(Pdb) kcfg = cfg.CONF.keystone_authtoken << Exception is happening here

So I don't understand what causes this error. Is there some limitation that is not letting it go further?

Just to summarize, if this is not expected to work with any other core plugins other then ML2, would be nice to have it in the future.
