Re: HA configuration, the reason as alarm event ?

Thank you, @nikolay.semov

Thanks to you, I kept up with the definition about Primary Backup.

However, I'm confused after seeing the URL you linked.

Basically, dual protocol is using just "2" devices, for example, Active/Standby.

So, I think that NSRP is also same meaning.

In the URL, the sentence was appeared at Backup definition : if other devices are in Master or Primary Backup

It means it is using 2 or more devices? even if it(NSRP) is dual? 

Am I thinking incorrectly?

Regards,

plus,

Do you think that its alarm is good status even though it indicated "critical".??
