"For example, suppose you have routing groups in Hong Kong, London, and Chicago. If your first Exchange 2007 server is deployed in Chicago, it makes sense to establish the first routing group connector to a bridgehead server in Chicago. However, if you then deploy an Exchange 2007 server in Hong Kong, when messages are sent from users whose mailboxes are on Exchange 2003 servers in Hong Kong to users whose mailboxes are on Exchange 2007 servers in Hong Kong, the messages will be routed through Chicago.

Getting to know the legacy Routing Group Connector in Exchange 2007
Getting to know the legacy Routing Group Connector in Exchange 2007:
"For those of you running bigger organizations, you may need to have multiple legacy RGCs. There are several things to consider before you do this, and as usual, the Exchange team blog tells you all you need to know. Before you go run off and read that link, though, here's a summary of the highlights:
Add the legacy bridgehead servers to the "ExchangeLegacyInterop" group so they have the proper permissions to authenticate to the Exchange 2007 HT servers

For small organizations, having a single legacy Exchange server connecting the legacy portion of the org to Exchange 2007 probably isn't that horrible, but in a larger org you may need to specify additional bridghead servers. The answer is found, of course, in the Exchange Management Shell.

Implementing Exchange Server 2007 for coexistence with Exchange Server 2003:
"Exchange 2003 servers use Link State Routing to exchange routing table entries for the path that messages will take through the exchange organization. A routing group master collects information about the status of other Exchange Servers and creates a small table in memory, the Link State Table (LST). The LST is then distributed to other Exchange Servers and will be updated at fixed intervals. Based on the Information about the status of other Exchange servers, a lost connection to another Exchange Server will be saved in the LST and Exchange tries to route the message over another Exchange server to the destination.
Link state routing is not used by Exchange 2007 Hub Transport servers and Exchange 2007 can't propagate link state updates. When a Hub Transport server sends an e-mail to another Active Directory site where a Hub Transport server cannot be contacted, the Hub Transport server does not recalculate the route. Hub Transport servers always try to communicate directly with other Hub Transport servers.
If there is more than one Hub Transport Server in a site, messaging traffic is automatically load balanced and the sending Hub Transport Server tries to reach each Hub Transport Server in the destination site before the connection fails.
When the connection to the destination site is unavailable, Exchange Server 2007 uses the associated site link costs to an Active Directory site to deternmine the closest site to send the mail to. This behavior is known as queue at point of failure.
If multiple routing paths exist between the default Exchange 2007 Routing Group and any Exchange Server 2003 routing group, Link State updates must be suppressed to ensure that no message loops occur when a route is recalculated. Microsoft recommends suppressing Link State updates if multiple connections exist between Exchange Server 2007 and 2003. It is possible to disable Link State updates through a registry patch. Configuration changes such adding a connector in the Exchange organization is still propagated by using the Link State information.
