Or you'll have to revert to what you did before dhcp filtering switches.

Which was watch for replies from rogues and then update your mac filters 
accordingly or drop the host onto a quarantine vlan. should work quite 
well for rogue RAs and rogue dhcpv6 servers.

Obviously it's reactive rather than proactive but it can be quite 
effective if automated.
