A customer has an SRX with 2 virtual routers in packet mode. There are no interfaces in the default instance. I have been asked to confugre Jflow to monitor traffic of one of the interfaces within one of the VRs. The sampling server is routable from this instance. Is there a way to get this to work without having a loopback interface in the default instance and having to perform route leaking? I know this is acheivable with route leaking but this is not desirable in this case.
Also it appears the sampling configuration within the routing instance (routing-insance r1 forwarding-options sampling) has no function, only the global sampling configuration (forwarding-options sampling) seems to work.
