我现在有一个服务部署在不通的端口上，在实现其通过WCF路由来交替调用时，出现了问题，只能调用的一个服务；请大家帮忙看看，配置文件如下：

路由端配置：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>

<services>
<service name="System.ServiceModel.Routing.RoutingService" behaviorConfiguration="RoutingBehaviors">
<endpoint name="nDB2" address="DB2" binding="netTcpBinding" contract="System.ServiceModel.Routing.IRequestReplyRouter" />
<!--使用的是EndpointName-->
<endpoint name="nDB1" address="DB1" binding="netTcpBinding" contract="System.ServiceModel.Routing.IRequestReplyRouter" />
<host>
<baseAddresses>

<add baseAddress="net.tcp://localhost:9002/V1/Routing"/>
</baseAddresses>
</host>
</service>
</services>

<behaviors>
<serviceBehaviors>
<behavior name="RoutingBehaviors">
<serviceDebug includeExceptionDetailInFaults="true"/>

<routing filterTableName="FilterTable1"/>
</behavior>
</serviceBehaviors>
</behaviors>

<routing>
<filters>
<filter name="FilterTest" filterType="EndpointName" filterData="nDB1" />
</filters>
<filterTables>
<filterTable name="FilterTable1">
<!--backupList :备份-->
<add endpointName="TestEndpoint" filterName="FilterTest" priority="1" backupList=""/>
<add endpointName="BackupServerA" filterName="FilterTest" priority="2" backupList=""/>
</filterTable>
</filterTables>
<backupLists>
<backupList name="backupA">
<add endpointName="BackupServerA" />
</backupList>
</backupLists>
</routing>

<client>
<endpoint address="net.tcp://localhost:8001/ServiceHost" binding="netTcpBinding" contract="*" name="TestEndpoint"/>

<endpoint address="net.tcp://localhost:8002/ServiceHost" binding="netTcpBinding" contract="*" name="BackupServerA"/>
</client>

</system.serviceModel>
</configuration>

客户端配置：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>

<client>
<endpoint address="net.tcp://localhost:9002/V1/Routing/DB2" binding="netTcpBinding"
contract="IDuplexSessionRouter"
name="DuplexSessionRouter" />
<endpoint address="net.tcp://localhost:9002/V1/Routing/DB1" binding="netTcpBinding"
contract="ServiceHost.ITest"
name="DB1" />
</client>
</system.serviceModel>
</configuration>
