If the issue is flooding to your interface IP, that's not a relevant 
countermeasure.  You're pretty much limited to asking the upstream to 
filter traffic to your interface IP, or asking them if you can renumber 
the interface into non-globally-routed IPs.  If they're unwilling to do 
either, "you've chosen the wrong transit provider" and should start 
shopping for replacements.
