Is there something like RA filtering on switches yet, so end users can be filtered? Just like the dhcp stuff thats available on most switches nowdays... ?
Its as annoying as fake DHCP servers...
Per customer VLAN isolation (common to solve DHCP server issues). You can also perform *some* filtering today for multicast addresses, but not the specific packets themselves from what I've seen. This is a big implementation change. I've had lengthy discussions with the DSLAM vendors who said, "VLANs are stupid and as bad as PVCs," about their ability to filter RAs and DHCPv6. -Jack
