Thomas Bachman 1af8d44586 Consult Host Domain Mapping for External EPG
When creating L3 Out using the AIM library, consult the
Host Domain Mapping V2 table to determine which VMM Domains
to associate with the external EPG. Only VMM Domains of type
'OpenStack' are used, and only wildcard host entries (i.e.
entries where host is '*') are used. If there are no wildcard
mappings for OpenStack VMM domains, then all OpenStack VMM
domains are associated with the external EPG.

README.rst

Group Based Policy (GBP) provides declarative abstractions for achieving scalable intent-based infrastructure automation.

GBP complements the OpenStack networking model with the notion of policies that can be applied between groups of network endpoints. As users look beyond basic connectivity, richer network services with diverse implementations and network properties are naturally expressed as policies. Examples include service chaining, QoS, path properties, access control, etc.

GBP allows application administrators to express their networking requirements using a Group and a Policy Rules-Set abstraction. The specifics of policy rendering are left to the underlying pluggable policy driver.

GBP model also supports a redirect operation that makes it easy to abstract and consume complex network service chains and graphs.

Checkout the GBP wiki page for more detailed information: <https://wiki.openstack.org/wiki/GroupBasedPolicy>

The latest code is available at: <http://git.openstack.org/cgit/openstack/group-based-policy>.

GBP project management (blueprints, bugs) is done via Launchpad: <https://launchpad.net/group-based-policy>
