No change. Did you test it?Use LOOPBACK ip Address as Router-ID:
* R1, /routing ospf instance set [ find default=yes ] router-id=192.168.2.1
* The same in all others Routrers
This will solve all your problems
For me, on RB2011-UAS-2HnD works normal.NTP don't work on RouterOs 6.11.
Several ntp servers tried to no avail.
After a few hours, after reboot
It's last option in Frequency selectbox (auto).Where is the setting for the auto frequency selection? can't seem to find it anywhere
