Router's Broadcast?

Question

Why broadcast packets are not forwarded across the router ?

Answer 1

This is by design. If routers passed all broadcast messages, the network would quickly become totally saturated with broadcast traffic.

In most cases, the only broadcast traffic that ever needs to pass a router is DHCP broadcasts when the DHCP server is located on a separate subnet. To enable that, add a "helper" address to the router configuration. The helper address is simply the address of the DHCP server. When the router sees a DHCP broadcast it will pass the DHCP traffic to the helper address.

Answer 2

One of the uses of routers is to limit the broadcast range between computers on large networks.

If you want a router that passes on broadcast you need to buy one that is (i think) RFC1245 compliant... or if you are using a computer running a RAS you need to configure it to allow the traffic across... these routers can allow the broadcast but will still decide wheather a unicast need to cross or not.

good luck..
