Yes, the problem traffic is the broadcast storm created when the issues occur. so having the BUM filter in place limits the total amount of that traffic that can occur preventing it from overloading...

As far i know you can't do it on MPC4E, possible with Multi-rate MPC7E but don't think they can do 1/10G , they are higher bandwidth ports. Your best option would be MPC3E with 10x10G MIC and 20x1G MIC...

You are right, that hierarchy for the filter is only available in family bridge. Would you be able to move the layer 3 interface to an IRB and have the physical interfaces using family bridge and a...

Depending on the features you need, the ACX5048 may be a good fit. These ports are either GE or XE and you only need to license the number of XE that you use.
