Broadcast address is 255.255.255.255 means that if your router int has an ip address of 10.10.0.0 and if you want to send a broadcast to your all hosts in that network, the router by default will send a broadcast not to 10.10.255.255 but to 255.255.255.255
So, on the interface if you give the command "ip broadcast-address 10.10.255.255 ", the router will now display "Broadcast address is 10.10.255.255" under sh ip int and send broadcast to this address only, not 255.255.255.255 anymore.
-my VLAN with 4 subnet addresses (a primary with 3 secondary's)
-when a machine on one of these subnets sends a broadcast the router hears it
-then, because it is configured with Broadcast address is 255.255.255.255 - it will send (or resend even??) the broadcast that it heard to 255.255.255.255 - so all devices in all subnets will receive it? The entire VLAN.
-Or, does the router have to originate the broadcast - but they don't do this?
-Or, does the specific application on the workstation have to generate the 255.255.255.255 or 10.10.255.255?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
