CSCsc49637

Symptoms: If a PPPoE client session is timed out (e.g. due to a network outage), and a restart of the 
session is subsequently unsuccessful (e.g. because network outage persists or the PPPoE server has 
not timed out the prior session) and if the user then manually clears the session, then the router will 
no longer be able to bring up this session until a reload is performed.

Conditions: This symptom has been observed when the PPPoE session is unexpectedly interrupted 
with Cisco IOS Release 12.3(8)T8 or Release 12.3(11) T5. The next feature also needs to be 
configured.

Workaround: Use the following procedure:

Reload.

Do not configure the DDR feature for the PPPoE session. This problem is limited to PPPoE 
client sessions using the DDR feature.
