Configuring Failover to Backup Media If a Junos OS Process Fails
date_range
21-Mar-23
For network devices with redundant Routing Engines, you can configure the device to switch to backup media that contains a version of the system if a software process fails repeatedly, or to the other Routing Engine.
To configure automatic switchover to backup media
if a software process fails, include the failover statement
at the [edit system processes process-name] hierarchy level. If this statement is configured for a process,
and that process fails four times within 30 seconds, the device reboots
from either the alternative media or the other Routing Engine.:
content_copy zoom_out_map
[edit system processes] process-name failover (alternate-media | other-routing-engine);
The value for process-name should be one of the valid process names.
