I don’t know is this the right way to ask this question. But anyway my question is when we configure L3 switchport as a routed port and it’s connected to a another L3 switch. Does that routed port forward broadcast traffic from it.

Please someone help me with this question. Thanks


Routed ports do not forward broadcasts. Broadcast domains are layer 2 constructs and do not cross layer 3 boundaries.


In addition to Ron's answer:

There are two different broadcast types for IPv4:

  • the limited broadcast to that generally cannot be forwarded to another subnet
  • the directed subnet broadcast with the subnet prefix and all host bits as 1, e.g. for - directed broadcast aren't forwarded by default, but many routers and L3 switches can be configured to do so.
