interesting multicast packet
Hi, my google-fu is failing me, but maybe one of you knows. After some troubleshooting around a Juniper SSG cluster today, we found that a windows server on the trust side of the SSG cluster is emitting UDP packets towards ff08::2.8083 (UDP, payload length 21) ff08::2 = all routers, organization-scoped These packets are sent about every 61 minutes, and caused some interesting issues here as the *passive* SSG leaked them out towards the router, leading to the NSRP MAC address showing up on the wrong switch port, causing short hickups. But that's not what I'm wondering about - I'm more curious about that sort of packet - what is that? What is it used for? Which process is emitting it, and what is it trying to achieve?

Does the windows machine run legato networker och similar backup service? Nothing of that sort. It's an internal management system, so something with netapp or vcenter would be possible. Backup is done with DPM, so it's not that... Gert Doering -- NetMaster -- have you enabled IPv6 on something today...? SpaceNet AGVorstand: Sebastian v.
