There may be a zillion use cases. But there is not critical mass for deploying this feature or other flooding reduction features. The time to solve this problem was back BEFORE people decided to repurpose BGP to solve their problems.  Now, it’s a classic ‘installed base’ problem. People will only consider alternatives if an alternative path represents less pain than the established path. We’re not there. BGP wins.


> PS. It is true that folks even running 10 racks think BGP is the only choice for the underlay but to me this is failure of deployment folks in vendors to properly position each dynamic routing protocol then nothing else. 


Well, we can blame marketing all we want.  All I know is that we, as a group, failed to come together and present a unified front with interoperable implementations. That left us in a position where marketing is pushing rocks up hills and customers are waiting for the dust to settle.
