Hello,

Have You tried to duplicate Your LS IP on master system lo0.0, and explicitly set "source-address" for each LS-mapped Jflow instance to be one of these duplicated IPs?

if You worry about leaking these IP to Your IGP, then JUNOS has tools to selectively disallow lo0.0 IP into IGP.

Thanks
Alex

Hello All,

We have an MX480 configured to export IPFIX flows to a server. Now, we have 
created some Logical Systems on the router to provide something like a “virtual 
router” to some of our customers on this location.

I have now configured some of those instances to export flows to the same flow 
server, but the objective is to monitor each logical system as a different 
router. But, I realized that all flows are going with the same “source router” 
and is the master instance source address, as explained in the documentation 
bellow:

http://www.juniper.net/documentation/en_US/junos16.1/topics/example/active-monitoring-on-logical-systems-configuring.html

The question is, has anyone had this claim yet? Is there any way to configure 
the router to send the flows with different source addresses per logical system?

Any help will be appreciated.

Thanks
