Two ISDN lines as a backup to the Leased line

If I were to use two ISDN lines to backup the existing leased line, over the router config, how can I configure it ?

Is there any sample configuration for it ?

Re: Two ISDN lines as a backup to the Leased line

Hi,

There are alot of examples of using ISDN as a backup for leased lines.

Start looking at this URL:

http://www.cisco.com/en/US/customer/tech/tk801/tk379/tech_configuration_examples_list.html

When configuring your solutins, use multilink ppp so that both your lines will be used.

Hope this helps;

Pl. visit following url for config.

Just configure the other BRI line same way as the one configured in above config.
