Description (partial)

Symptom:
Guest clients cannot connect (get excluded) in wireless setup with WLC as Anchor controller and veWLC as Foreign controller, if the guest wlan is configured with aaa-override and IPv6 redirect ACL.

Conditions:
This behaviour is observed when the guest wlan is configured with aaa-override and an IPv6 redirect ACL. 
When a guest client connects, WLC anchor controller is sending to veWLC foreign a malformed IPV6 ACL name in Export Anchor Ack message, which results in veWLC foreign excluding the client.

Recovery:
The client that was excluded needs to wait for the exclusion timeout to expire and then connect a guest wlan that doesn't have aaa-override and IPv6 ACL configured at the same time.
