Configuring Failover to Backup Media If a Junos OS Process Fails

 

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.:

The value for process-name should be one of the valid process names.
