If the only bridgehead server in a routing group is down, there are no other routes for the mailbox server to choose. > But this would mean that the link state table information is > only shared between connector servers? No, it's shared between all servers in a routing group, only one server is the routing group master for the link state data. > Surely the mailbox server would need to have knowledge of the > bridgehead servers and their priority? It does and stop calling me Shirley. > Otherwise how does the mailbox server know what bridgehead > server to send messages to if there were two in a routing group ? See above answer regarding LSA information being shared among all servers. > Is there a good book or technet reference etc that you can > recommend that details how exchange uses alternate routes > when connector servers die? Donald Livengood an HP consultant gave a 2 hour presentation on the subject in fast talkin redneck at a Compaq Exchange Academy I attended. I think he might have given a similar presentation at MEC last year or the year before.. Might check Microsoft's website for the slide deck. With only 3 mailbox servers I ponder the need for bridgehead servers or for separate routing groups. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
