Description

lets imagine the following situation:
There is 5 interfaces (vlans) and 5 vrrp groups and everything working fine.
I'm going to create 6th vlan + 6th vrrp group.
if I've created 6th vrrp group but forgot to create 6th vlan interface and executed "commit" command, the VRRP will stop working completely!

Here is VRRP log:
