Resolution:
We do not recommend importing and exporting ">" in your RVRD.  Instead, we highly recommend that you use more specific subject names such as FOO.>, NAME.>, etc., as this will prevent some RV protocol messages from being unnecessarily forwarded from one subnet to another.  In addition, it will help prevent a listener on ">" from flooding the network with all messages received from every subnet.  By being more specific with subject names, you can dramatically reduce traffic on a subnet.
