single BD for shared Heartbeat

[JFF]

We have several F5 clusters running on VMware.  We are considering using a single EPG/BD for all the different HA interfaces.  So cluster1 (2 nodes) could use IPs like 1.1.1.1/30 1.1.1.2/30, cluster2 (2 nodes) could use 1.1.1.5/30 1.1.1.6/30 etc ...

My concerns is the fact that they would use same BD and that BUM traffic would be flooded to all devices in BD.

Is it a valid concern? Does that design make sense?

Is there a specific reason why you need to flood the BUM traffic? By default there won't be flooding on ACI.

Even if you were to flood for the BD, I don't see this being a problem.
