Bug Description

[Existing problem]
Current BGP dynamic routing proposal [1]_ doesn't have support for route aggregation. Route aggregation could be extremely useful in reducing the size of the routing table and improves CPU utilization [2]_.

- Add route-aggregation support to BGP dynamic routing.

- Route aggregation is good as it reduces the size, and slows the growth, of the Internet routing table.
- Amount of resources (e.g., CPU and memory) required to process routing information is reduced and route calculation is sped up.
- Route flaps becomes limited in number

[What is the enhancement?]
- - Additional API, CLI and DB model will be added.

The feature which this RFE depends on is not yet implemented.
It is valid as a feature request, but the requested feature can be implemented during the current proposed implementation.

We need to revisit this after BGP-DR blueprint completes.

Thanks for the update. I think it's fair to say that until [1] is feature complete (blueprints implemented - i.e. basic code, tests, docs), bugs [2-7] are blocked. My suggestion would be to go and yell/help the assignee/approver of [1] and make sure that the work can complete successfully asap so that we can start focusing on 2-7 knowing on what grounds we can continue building.

This should be considered with Host Aware IPAM [1]

This will become more of a priority when DVR can route for a local fixed IP and we start sending announcements for each fixed IP. I think there is a host-aware IPAM component to this as well

Assumed that by the end of Newton (or sooner if possible) the BGP repo is up and running and rock solid based on the efforts put into Mitaka, I see no reason why these requests should not be vetted and addressed by the BGP team directly. So please make a recommendation.
