Can we restrict the high broadcast traffic from interface in Cisco ASR9k and 7600 routers? If so, what configuration we should apply?

  • Are you sure it is coming from the routers? Routers do not propagate broadcasts unless you have enabled ip directed-broadcast on an interface. The routers themselves would only use broadcast for ARP, but that would be necessary for the proper functioning of the network. – Ron Maupin Oct 3 at 12:46

You can't simply drop broadcast traffic. You need to locate the source(s) first, then you can filter appropriately - ideally close to the source. Better yet, identify the problem causing the broadcasts and fix it.

    It could limit it using storm control. But i agree with you. – user56700 Oct 3 at 11:59
  • @user56700 Yes, a broadcast storm is something different and must be controlled, even with significant drops. I didn't have the impression the OP was referring to that though. – Zac67 Oct 3 at 18:07
