Hello,
my name is Nelson and I´m from Portugal.
I have a customer that will install several cisco 887 VAMG2 that have a L2TP tunnel through a ADSL conection. The idea is that when the ADSL connection fall the router establish a GSM connection and the tunnel L2TP establish throght GSM.
This seams to work but only with the dialer persistent command. The question is that the client does not have unlimited traffic to GSM network so, the connection could not stay always up.
The same customer already have cisco 1841 with this solution working but with this new routers, only seems to work with dialer persistent.
Any idea ? Urgently

With this basic configuration, it seems like the router does not do anything
