BUM Traffic
Broadcast unknown-unicast and multicast
BUM traffic collectively refers to broadcast, unknown unicast, and multicast.
In context
It describes forwarding that requires replication to multiple endpoints in an overlay. Replication and suppression methods vary with control methods and settings.
Example
Replicating one internal broadcast to multiple VTEPs may also increase transmission volume on underlying links.
Key distinction
Examine virtual broadcast scope together with actual replication overhead.
