I have a small LAN comprising a Windows 7 Ultimate x64 PC, 2 Windows XP Pro x86 PCs and an Asus router.The Win 7 box has IPv6 enabled. There are no other IPv6 enabled devices on the LAN.

In my firewall I see numerous requests originating from the Windows 7 PC, which are for the Multicast address ff02::1:ff, which is a Solicited-Node address query and has a scope of 2 which equates to the local link.

As far as I knew local link addresses are filtered by routers, hence local link. Given that situation I'm wondering why I'm seeing these queries being generated to various addresses?

Any ideas?

If they sold you an x54 machine, you should take it back to the store ;-) – Daniel Beck Dec 30 '10 at 13:31

Can't beat those x54s, they're beasts ;-) – Pulse Dec 31 '10 at 6:06
When you say "In my firewall I see..." where in your network is the firewall? – Spiff Jun 27 '11 at 0:42

troubleshoot...go to another port on the router with wireshark and see if you can find the requests...often consumer grade "routers" have an integrated four port switch that acts like a dumb switch plugged into a single "router" port and a wan port.

meaning that the LAN ports are switched not routed – aking1012 Dec 30 '10 at 17:00
Thanks for the suggestion. I've been doing some analysis with Wireshark but I'm still none the wiser. The router is running custom firmware, which does a pretty good job of differentiating the port characteristics. I'll keep looking... – Pulse Dec 31 '10 at 6:09
