Database syc failed between Master and Master-Standby. VRRP working !!!

[ Edited ]

Master and Master-Standby database syncronization failed. VRRP is functioning properly.

You don't have master redundancy configured properly. You should see two controllers from the master; the master and the standby

Soory to say I disconnected the standby and remove the VRRP steup. Once I will make the setup again I will share the update.

Master redundancy has to be setup correctly for database sync to work.  That is different from VRRP redundancy.

If you type "show switches" from the master and you do not see the master AND the standby, master redundancy is configured wrong....
