Configuring ADSL backup

[rrevuru]

Hello:

I have primary T-1 connection coming to 2611XM router. I want to use ADSL connection as a backup connection to T-1. I have one unused fastEthernet port on the cisco 2611XM.

Please i need suggestions of configuring the ADSL as backup.Any pointers to the websites would be appreciated.


Thanks,

You can configure the spare ethernet interface with the "backup" command and configure it so that when the T-1 interface goes down, the spare ethernet interface comes up.
My suggestion would be to configure the spare ethernet interface to the correct specs for the ADSL and then use the "backup" command. Also there is a preempt option with this command so that you can configure it so that if/when the T1 interface comes back up the ADSL or ethernet interface will suppress once again.

Hope this helps.

yes. You can set up your crypto in config mode.

interface f0/1
no ip address
crypto map backup
dial pool-member 1

int dialer 1
ip address neogtiated (if your using dhcp)
encap ppp
ppp auth pap chap callin
ppp chap host name "don"
ppp chap password "johnson"
ppp pap sent username "don" password "johnson"
dialer-group 1


You may have to set up pppoe if you provider is using it

vpnd enable
vpdn-group pppoe
request-dialin

interface f0/1
no ip address
crypto map backup
protocol pppoe dial pool-member 1

int dialer 1
ip address neogtiated (if your using dhcp)
encap ppp
mtu 1492
ppp auth pap chap callin
ppp chap host name "don"
ppp chap password "johnson"
ppp pap sent username "don" password "johnson"
dialer-group 1

Something to this nature, I'm doing it off what memory I have left tonight.

You can do a search on adsl and pppoe configurations

0.0.0.0 0.0.0.0 dialer1 250 However your routes are.
