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.
