Hi,
We are currently utilising L2TP to tunnel PPPoE traffic and we are seeing some irregularities. How does Cisco IOS handle the following scenario:
user logged on and authenticated via PPPoE and Radius. The user sends regular PPP echo messages. For some unknown reason the user then sends a PPP LC configuration request with a different magic number to the one used for the current established session. My question is how does IOS handle this, I would expect the router to terminate the current PPPoE session by sending a PADT packet to the source as the magic numbers are different but I need this confirming. Unfortunately, I can't get the configs of the terminating router as we don't manage it.
