I have a customer connected to my Cisco 3560 switch via Gigabit
Ethernet, recently I noticed that he is broadcasting IPv6 packets
such as LLMNR, DHCPv6 and ICMPv6 it seems that the customer is
connecting a Vista machine that has some IPv6 services enabled
(some IPv6 services are enabled by default on Vista)
How can I block such broadcast from entering my network?
By the way there is no firewall in this setup, just a switch to switch.
