Hi,
short story, I installed on a site a cisco 819G with pre configured working cellular 0 interface like WAN-2 Backup.
On site I finalyse the config for the WAN-1 primary. Working.
The issues is that I did not test the failover on site , but now i realyse that the cellular interface 0 backup doesn't go up anymore in case of wan 1 faillure.
please see the conplete config attached.
I think something is wrong with the dialer-group and conflict between cellular 0 interface and dialer 1 interface for PPPOE primary connexion.
Your help will be appreciated.
