Two ISDN lines as a backup to the Leased line

[fkseow]

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 ?

Hi,

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

Start looking at this URL:

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

Hope this helps;

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