在两个独立的子网中使用Hazelcast集群，如何桥接这两个不同的集群？

<hazelcast>
  ...
  <network>
    ...
    <join>
      <multicast enabled="false"/>
      <tcp-ip enabled="false"/>
      <aws enabled="false"/>
      <discovery-strategies>
        <discovery-strategy enabled="true" class="com.hazelcast.aws.AwsDiscoveryStrategy">
          <properties>
            <property name="access-key">YOUR_ACCESS_KEY</property>
            <property name="secret-key">YOUR_SECRET_KEY</property>
            <property name="region">us-west-1</property>
            <property name="tag-key">YOUR_TAG_KEY</property>
            <property name="tag-value">YOUR_TAG_VALUE</property>
          </properties>
        </discovery-strategy>
      </discovery-strategies>
    </join>
    ...
  </network>
  ...
</hazelcast>
