Add route manual summarization feature to ExpressRoute which advertise summarized routes to on-premises router
Currently ExpressRoute does not support manual route summarization, for example:
Currently the routes are learning with /24 which needs to be summarized to /16
Customer is not able to summarize the route in Azure, and they will need to summarize on their on-premises devices through BGP, before further route propagation.
Please consider to add such feature in ExpressRoute.
