Hi there,

Try configuring the dialer interface and put in the command "backup interface xyz" and that should sort it.

I've done thing having an ethernet interface as a backup to a tunnel interface and it works a treat.

Hope that helps,

Re: ISDN and Dialer Profile

Hello,

have a look at the following configuration example:

interface FastEthernet0/0

backup interface Dialer1

ip address 192.168.1.1 255.0.0.0

mpls ip

!

interface Dialer1

ip address 172.16.1.3 255.0.0.0

encapsulation ppp

dialer pool 1

dialer remote-name Remote_1

dialer string 1234

dialer persistent

dialer-group 1

mpls ip

ppp authentication chap

This sample configuration is from the following document/guide:

ISDN Backup in MPLS Core

Re: ISDN and Dialer Profile

thanks everyone,

i will illustrate my problem more clearly,

my router is connected to a modem and that modem is connected to a MPLS cloud (ISP) and same situation is on both ends.

so suppose mpls not working, no communication, there is no way i can tell the router to know that the mpls is not working since the router is connected to the modem and since it's ethernet it will never know? so i hope it's clear what i am trying to get... thanks in advance
