DSL backup whit ISDN

pgasol
Level 1
Level 1

Hi, I want to configure a 1700 router to connect to Internet by DSL and ISDN backup.

I need that the dialer1 and the atm0.1 have the same IP because we have a web server in our LAN.

I have configured the router but it doesn't work, when I shutdown the atm interface the dialer interface is :

sh interfaces dialer 1

Dialer1 is standby mode/disabled, line protocol is down

Hardware is Unknown

Interface is unnumbered. Using address of Loopback0 (212.81.207.2)

MTU 1500 bytes, BW 56 Kbit, DLY 20000 usec,

reliability 255/255, txload 1/255, rxload 1/255

Encapsulation PPP, loopback not set

DTR is pulsed for 1 seconds on reset

Last input never, output never, output hang never

Last clearing of "show interface" counters 00:53:54

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

Queueing strategy: fifo

Output queue: 0/40 (size/max)

5 minute input rate 0 bits/sec, 0 packets/sec

5 minute output rate 0 bits/sec, 0 packets/sec

0 packets input, 0 bytes

0 packets output, 0 bytes

This is the show run of the router

Can anybody help me please?

Hello,

just to make sure: do you shutdown the subinterface or the physical interface ? I am just asking because shutting down the subinterface will not trigger the dialer backup interface, this is just a Cisco-specific feature. Try and shutdown the physical interface (ATM0).

If that doesn't help, can you post the output of :

debug dialer events

after trying the failover ?

Regards,

GP

Many thanks, I have tried that you told me and it works now
