Description (partial)

Symptoms: If 32k dual-stack sessions are configured on a PTA device such as a 
Cisco ASR 1000, the router may crash when the sessions are brought down.
 
Conditions: This symptom is observed when both the PPPoE client and the PTA 
are Cisco ASR 1000 routers. The client crashes when the <CmdBold>test 
pppoe<noCmdBold> command is entered while trying to bring up 16K dual-stack 
sessions on the PTA device. This symptom is more likely to be observed when 
the preferred lifetime and valid lifetime of the assigned prefix are 
configured to be  equal. The crash may occur even if the lifetimes are not 
equal, but it is less likely.
