Simply doing a shutdown on an interface will not bring up the backup line in
this scenario as it is administratively down. You would need to unplug the
serial line from the router or change the encaps on one side to make it go
down other then adminstrativly

Hy Guys,
I have a configuration for my Cisco Router 3640 on the BRI that it is a
backup interface for Serial line:
****************************************************************************
************
interface Serial1/0
description Collegamento CDN 512 Kb con sede Milano-San Martino
ip address 132.96.140.2 255.255.255.0
backup delay 5 20
backup interface BRI2/0
no ip directed-broadcast
no ip mroute-cache
****************************************************************************
*************
The configuration for the BRI2/0 is :
****************************************************************************
****
interface BRI2/0
description Collegamento di backup linea MI-ROMA
ip unnumbered FastEthernet0/0
no ip directed-broadcast
encapsulation ppp
dialer map ip 132.96.87.1 name R01rxxxcomm1itl broadcast 5843
dialer load-threshold 1 outbound
dialer-group 1
isdn switch-type basic-net3
