- Cisco IOS
Known Affected Releases
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.
