With these patches that handle routing based on certain ranges of the address, it seems that this is well aligned for that adoption. I'm not too familiar with how classic does it's mappings, but I did briefly look at the AddrRange class and I suspect that I understand what you mean. It remains to be seen if this patch will go through, but it's what I am pushing right now. The address based mapping with bitSelect seems like a good way to handle the routing problems. You can thank Nilay for this solution if you see him on the boards anytime soon; kudos go to him for this. - Brandon ----------------------------------------------------------- This is an automatically generated e-mail.
