    HI all,

     

     

    Can someone show me the configuration to prevent broadcast storm on MX480 (VPLS environment) such as EX can do as per this url http://www.juniper.net/techpubs/en_US/junos10.3/topics/example/rate-limiting-storm-control-configuring.html

     

     

    thanks and appreciate someone feedback.

     I am afraid there is no configuration for preventing broadcast storm like in EX2200.

    But let me check further.

    Hello,

    For VPLS on MX, You need to use VPLS flood filter with appropriate policer(s):

     

    aarseniev@mx# show firewall family vpls filter flood-filter-10M 
    
    term broadcast-traffic {
    
        from {
    
            traffic-type broadcast;
    
        }
    
        then {
    
            policer POLICER-BUM;
    
            accept;
    
        }
    
    }
    
    term multicast-traffic {
    
        from {
    
            traffic-type multicast;
    
        }
    
        then {
    
            policer POLICER-BUM;
    
            accept;
    
        }
    
    }
    
    term unknown-unicast-traffic {
    
        from {
    
            traffic-type unknown-unicast;
    
        }
    
        then {
    
            policer POLICER-BUM;
    
            accept;
    
        }
    
    }
    
     
    
    [edit]
    
    aarseniev@mx# show firewall policer POLICER-BUM 
    
    if-exceeding {
    
        bandwidth-limit 10m;
    
        burst-size-limit 10m;
    
    }
    
    then discard;
    
    
    routing-instances {
    
    	<RI-NAME> {
    
            forwarding-options {
    
                family vpls {
    
                    flood {
    
                        input flood-filter-10M;
    
                    }
    
                }
    
            }
    
        }
    
    }
    
    

     HTH

    Thanks
    Alex

    Hi -

     

    Woudln't the flood-filter also require a default term which accepts all?

     

    Thanks,
