Scheduled Reboot every Sunday morning

Hello All,

Can I get confirmation that the following code is good to achieve every sunday morning 4:30 reboot of the edge router? Will this automatically update the crontab config file?

set system task-scheduler task sunday-reboot crontab-spec '30 4 * * 0'

set system task-scheduler task sunday-reboot executable path /sbin/reboot

And what will be recommendation to reboot two routers setup in a redundant / VRRP mode? Will a 10 minute spacing of the reboot between the two be fine?

Also if someone can help with suitable cron config for every first sunday 4:30 of each month please. I have very little linux experience.

Thanks so much,
