At the outset of the poorly informed written in English
With Debian Linux, you can do two servers PPPoE, first turn off and turn the other on MT, but the PPPoE sessions are held without disconnecting customers.
It works like this: pppoe server and exits, and the sessions run until the client disconnects, new ones are no longer compiled on Debian, only on the new server PPPoE
He wants to do the same on the two MT and can not be. After the PPPoE server is turned off immediately disconnects all sessions.
How do customers not to disconnect and disable one PPPoE, turn to the second and new connection into a new, and old, were supported until they disconnect.
To sum up wants to start the second MT PPPoE server, and the first old man disable it in order not authorized the new connectivity, but that does not already disconnected the calls.
How to set the MT to not hung all sessions after the PPPoE server is turned off on the old MT
how to achieve the result is a gradual increase in the session and automatically switches to a new PPPoE client server.
