The issue occurs when a customer deploys PEM in an environment with multiple Routing Domains (RD) for subscriber traffic. The subscriber sessions are created successfully using RADIUS for subscriber traffic on RD 0. The traffic arriving on a VLAN associated with any non-zero RD does not match the session created with RADIUS, thus causing issues with identifying the subscriber traffic and applying the correct policies.
Subscriber traffic arriving on a non-zero routing domain will have issue with identifying the subscriber traffic and applying the correct policies.
This happens when PEM is deployed with subscriber traffic arrive BIGIP with multiple routing domains (i.e., multiple vlans)
there is not work around
This fix will treat subscriber traffic from any routing domain as if they are from RD 0, so that as long as the customer can ensure there will be no overlapping IP addresses between different routing domains, PEM will work just fine.
