Routing Group Connector question

    Question

  • Hello all,

    I have Exchange 2003 installed in a backend frontend topology.

    I have installed two CAS/HT servers. CAS roles are working fine. With regard to HT roles, when I do Get-RoutingGroupConnector it lists the name of one HT server. I read by default it creates only one RoutingGroupConnector and we have to add the second one. Can you post the syntax here for reference?

    Also, what are the steps I need to take to get HT functional after installing HT role in an Exchange 2003 coexistence mode? Is there a step by step procedure article available for reference?

    I read this TechNote but hard to understand though http://technet.microsoft.com/en-us/library/dd638103.aspx

    Thanks in advance

  • It depends on your design what you'll want to do:

    a) If you have both Exchange 2007/2010 Hub Transport Servers in the same site, then you'd want to add the second server as a source server for your Routing Group Connector to the Exchange 2003 environment by: Get-RoutingGroupConnector | Set-RoutingGroupConnector -SourceTransportServers "Server1.domain.com,Server2.domain.com"

    Set-RoutingGroupConnector

    b) If you have Exchange servers in 2 different Active Directory sites and would like to add a Routing Group Connector to facilitate quicker delivery paths, then you'd like to add another Routing Group Connector by: New-RoutingGroupConnector -Name "Interop RGC" -SourceTransportServers "Ex2010Hub1.contoso.com" -TargetTransportServers "Ex2003BH1.contoso.com" -Cost 10 -Bidirectional $true -PublicFolderReferralsEnabled $true

    Create Additional Routing Group Connectors from Exchange 2010 to Exchange 2003

    If b) then please also remember to suppress minor Link State updates as not to end up in a scenario with routing loops. How to Suppress Link State Updates

  • Thanks Jesper.

    i have only Exchsrvr 2003 in my setup. i have two HT servers in my setup and they are CAS too. Once I finished installing HT role on both servers, I did a Get-RoutingGroupConnector from Exchange management shell and the output list the first HT server routing connection in both direction. For example:

    Exchange 2010 -> Exchange 2003 and vice versa.

    i manually added the second HT server name by New-RoutingGroupConnector -Name <String> -SourceTransportServers <MultiValuedProperty> -TargetTransportServers <MultiValuedProperty> 

    i didn't added bidirectional switch as i want to have the similar naming convention for RoutingGroupConnectors as the default one. I didn't added cost either. What is the default cost? how is the priority accessed,higher or lower number has highest priority?

    In an Exchange 2003 coexistence mode, what are the steps to be performed for HT? I can't find a nice article which explains the steps.

     

    Thanks

  • You didn't tell if your Exchange Servers reside in one AD Site or more but I'm guessing you only have one and in that case you really should go for option a) instead of option b). Option a) is the proper way of doing things in your scenario.

    Hi Tom,

    To answer your question, the default cost is "1" for the Routing Group Connector created by Exchange 2010 when you install in an environment that already has 2003.  The lower cost routes are used before the higher cost routes.  I took the time to write out all the commands and describe the different scenarios in which you would use the different commands to make this all more clear: How to add additional servers to Exchange 2010 Routing Group Connector

    I would recommend you use the complete commands that contain the bidirectional switch and the public folder referral switches, that will make things a lot easier.

    Hope this helps,

    Chris
