I have 2 adsl lines. I want to use one of them as backup line. Primary is on fe-0/0/7 Backup link is on : at-1/0/0 interface
I searched kb and found configurations but could not run :
set interfaces fe-0/0/7.0 backup-options interface at-1/0/0.0
error: interface: 'at-1/0/0.0': invalid value
I also tried to configure it from GUI but same problem happened.
I have the latest JunOS on my SRX device.
The second questions is:
Can I load balance these 2 adsl lines?
AFAIK all physical interfaces can be configued with backup-option for Dialer interface (dl0) only & also i dont think we support load blancing.
