Radius load balancing not balancing

We've got a pair of LTMs (running 11.5.0) and I've been trying to set up load balancing for our radius servers which are authenticating our wireless traffic. We're using FreeRadius. We're using MSCH...

There are at least 2 solutions. One is to build and iRule and attach it to your iApp. See https://devcentral.f5.com/wiki/iRules.RADIUS__avp.ashx. The other is to apply the radius profile with persist-avp (tmsh create ltm profile radius radiusLB persist-avp). I believe the latter is more straightforward, but unfortunately it is not implemented in the f5.radius iApp in 11.5.

Thanks Martin. I am especially interested in the result when you create the following attribute-value persistence profile and attach it to your radius virtual. ltm profile radius my_radiusLB { defaults-from radiusLB persist-avp 1 }
