What rule is that? Is the routing within Wind River "convex"? Assuming it is, I don't see why you wouldn't make Wind River a single site, even if it is geographically dispersed.
Wind River has multiple sites with Internet connectivity that are connected via linked lines. If you think of two of them, you can picture a dumbbell shaped network. Our ISP is routing different parts of the Wind River network space to different locations.
In this configuration, the preferred path for global traffic between the two locations is to go over the leased line. This keeps the traffic inside the firewall, etc. However, if the leased line goes down (or one of the routers to it goes down, etc.), global traffic will fall-back to being routed over the global Internet... This is great because it lets me reach non-secure parts of the other Wind River site, even when my secure link is down. And, I can run a client VPN solution to get behind the firewall, if I need to. However, this fallback route breaks the concept that the site needs to be "convex" at the global scope. So, I need to have my two locations be two different sites. This has been discussed a few times on the IPv6 list before. So, I need to have two sites. I'm not wild about that, but it is required by our current scoped addressing architecture. However, I am not require to number those two sites from different /48 address allocations... And, if I change ISPs, I will need to renumber the entire network.
