Hi all


Windows 7 & Vista send of DHCPv6 packets to multicast MAC 33:33:00:01:00:02 (IPv6 ff02::1:2) and this packets received on interfaces from other VLAN (VLAN L2 without L3 SVIs). Also IPv6 send IGMP membership packets to L2 VLAN too.


How  disable it without igmp global turning off?

The problem remains relevant:

5 minute input rate 9165234 bits/sec, 6762 packets/sec

Sniffer shows lot of DHCPv6 packets to multicast MAC 33:33:00:01:00:02 from user VLAN.

It's not a problem, it's a protocol. Use it. Use IPv6 volunteerly before you will be obliged to.
