We have several realms configured to do round robin between two downstream radius servers. We have observed that our freeradius (0.8.1) servers are sending all traffic for a realm to the first server listed for that realm. I have seen in the logs where it does do failover however. Here's an example of how we have these realms configured:
Your realm configuration is correct.
Alan and I submitted *many* changes to the original round_robin code, and although I'm not positive...I think it ended up *not* being supported in the 0.8.1 release. I don't have the base 0.8.1 release running, though, so I'm not 100% sure on that.
It is fully supported in the CVS head. I have been testing the current implementation for quite some time and it is completely functional. If you are sure that it is not working, and can update to the CVS version...I would do that.
Just a note, the disbursement of requests will not necessarily be A-B-A-B-A-B, but you will get an even spread (i.e. A-B-B-A-A-B) as time approaches infinity.
