It's a pretty basic concept to connect to different servers from a Camel instance. It, however, depends a bit on how you have it configured/deployed. Given you have your Camel running in Spring inside your ActiveMQ, you can simply setup two camel-activemq components. You need to give correct broker URLs, queue names etc.
<bean id="localamq" class="org.apache.activemq.camel.component.ActiveMQComponent" >
<property name="connectionFactory">
<bean class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="vm://localhost?create=false"/>
<property name="userName" value="${activemq.username}"/>
<property name="password" value="${activemq.password}"/>
</bean>
</property>
</bean>
<bean id="remoteamq" class="org.apache.activemq.camel.component.ActiveMQComponent" >
<property name="connectionFactory">
<bean class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://otherserver:61616"/>
</bean>
</property>
</bean>
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="localamq:some.queue"/>
<to uri="remoteamq:some.other.queue"/>
</route>
</camelContext>
