Subject: vrf and multicast is broken in some cases

Hello,

We put two different ports into their own VRF, and then tried to run a multicast
sender on one and receiver on the other.  The receiver does not receive anything.

Is this a known problem?

If we do a similar setup with policy based routing rules instead of VRF, then the multicast
test works.

Thanks,
Ben
