Yes, the right solution would be to at least separate the VLANs and clean up this

Strange that you don't apply the logic of "the existing software is what there is" to the code deep inside hundreds of 
millions of hosts, but rather to obscure stuff that presumably hardly anyone uses.

If changing this software is so hard, what these people need is some filtering switches so the application multicasts 
get forwarded but the IP provisioning multicasts don't. No standards action required.

BTW, does this broken software run over IPv6, anyway?
