Symptom
With the Cisco ASR9000 used for BNG, the subscriber sessions may get stuck in "Connected" state.
Conditions
This was observed with the Cisco IOS-XR 5.2.2, when:
- the initiator "unclassified-source address-unique" is used
- the subscriber(s) generate more than 20pps during FSOL.
Workaround
The problem is not occuring if the "address-unique" feature is removed.
Change:
ipsubscriber ipv4 l2-connected
initiator unclassified-source address-unique
To:
ipsubscriber ipv4 l2-connected
initiator unclassified-source
