cache_eap

[Rouzier, James]

Thanks for the reply.

Our use case is to be able to run FreeRADIUS behind a “dumb” UDP load balancer that would load balance the RADIUS packets without having to look at the EAP state. We were hoping to leverage the eap cache for that purpose.

What limited use cases can caching EAP packets be used for?

      It doesn't work.

      On top of that, there's no benefit to caching EAP packets on proxy fail-over.  The cost to doing it is large, the benefit is small, and it works only in very very limited situations.
