<div><br></div></div></blockquote></div><div>Hmm....so if i get this correctly, you assign say <a href="http://192.168.4.0/24" target="_blank">192.168.4.0/24</a> to a customer, who then plug in into a switch and assigns static to all its users (or dhcp as the case maybe) and this the activity (including broadcast) by those users gets to you.<br>
<br></div><div>Yeah thats the normal and expected behaviour. A first thing to do is to limit the subnet you are assigning to customers to say /30 or /28 max. The prefix you assign to the customer would only be a broadcast within the customer end since broadcasts are within subnets. I presume you have a/some routing protocol(s) running at your say distribution and definitely at the core.<br>
<br></div><div>On a lighter note, if you have layer 3 devices at your customer premises, then you just need to run a few more layer 3 at the pops (high ends connecting to other sites). Even with the current setup, i am still wondering how you receive broadcast storm from the customer since they have their subnets? Perhaps the broadcasts is coming from devices directly connected on the switch at the pops(high ends)<br>
