Symptoms

The per-Session RADIUS Acct STOP message is forged based on the pool route domain, but is sent through the default one.

Impact

The BIG-IP system sends the STOP packets according to the default routing table instead of the configured route domain RADIUS server.

Conditions

1. Deploy the BIG-IP system with two route domains 2. Under each route domains you have a path to the RADIUS server. 3. Create Access Policy with a Logon Page, RADIUS Acct agent fallback-to-Deny ending. 4. Attach it to the virtual server. 5. Run tcpdump -i any port 1813 -ne on the BIG-IP system. 5. Navigate to the virtual server. 6. Wait 20 seconds till STOP packets arrive.

Workaround

None.

Fix Information

The BIG-IP system now sends the STOP packets according to the configured route domain RADIUS server.
