Public bug reported:

[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]_.

[Proposal]
- Add route-aggregation support to BGP dynamic routing.

[Benefits]
- 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.
