Coexistence Routing
Earlier in the chapter, the least cost routing algorithm was explored. This section looks at the impact of
Exchange 2003 coexistence on routing. The connector cost is comprised of the destination address space
as well as the site or connector cost. The cost can be thought of as the Exchange 2003 “ legacy ” Routing
Group Connector cost and the Exchange Server 2007 Active Directory site cost. The best route is the
route with the best legacy cost followed by the Active Directory site cost. Because of this design, routes
can stay within the Exchange Server 2007 routing group and go across site connectors with higher costs.
Consider the example in Figure 11 - 14 . A user in Site 1 on Exchange Server 2007 sends a mail to an
external recipient at exchangeexchange.com.
