Ah, I see. The VLANs are only private in the sense that we control which devices are attached to them. They are routed VLANs. (i.e. I did utadm -A to add the networks)
We don't span VLANs across switches. Our network is large, and the convergence in the case of a core switch failure would severely impact our availability and performance. The Sun Ray servers are physically remote from the client side, so we use DHCP forwarding on the client switches to private VLANs on the servers. Everything is redundant and the FOG functions flawlessly. We've done disaster recovery testing using this configuration, and everything works exactly as expected. -Bill ________________________________________ From: [EMAIL PROTECTED] [EMAIL PROTECTED] On Behalf Of Kent Peacock [EMAIL PROTECTED] Sent: Monday, May 12, 2008 7:12 PM To: SunRay-Users mailing list Subject: Re: [SunRay-Users] Trying to get a FOG going over 2 sites.

Did you use private interconnects, or were your Sun Rays on routable segments of your network? It's the routed *private interconnect* scenario that is not supported. Multicast is the least of the problems in that particular case.
