Re: dial backup interface using ISDN

Hello,

with the BACKUP INTERFACE command, the backup interface goes up when the primary interface goes down, independent on any (dynamic) rotuing protocol. Let´s say your primary line is serial 0 and your backup line is BRI0, your config would look like this:

interface serial 0

backup interface bri0

Check thsi link for more info, also on how to use the dial backup with dialer profiles:
