multisubnet listener

Good morning all ,

I have an alwayson instance with a multisubnet listener

I configured RegisterAllProvidersIP = 0 in order to register a single DNS entry

HostRecordTTL is configured at 1200 seconds

I would like if with this configuration I will have timoeout during the failover

if so how much time is needed for the application to connect to the lsitener

thanks
