What does a router normally do when it receives a broadcast?

When a router receives a broadcast, it typically does not forward it to other networks, as routers are designed to separate broadcast domains. Instead, the router will usually drop the broadcast packet and may send an internet Control Message Protocol (ICMP) message back to the sender if appropriate. This behavior helps to reduce unnecessary traffic and maintain network efficiency. In contrast, switches and hubs will forward broadcast packets to all devices within the same local network segment.
