State: open

When VRRP is in master state, other machine can enter with a higher priority, and the vrrpd only change state master to fault. Even when you are in master state, you must listen to requests to change the state to backup.

According with RFC 3768 section 6.4.3. - Master:
" If the Priority in the ADVERTISEMENT is greater than the
local Priority,
or
If the Priority in the ADVERTISEMENT is equal to the local
Priority and the primary IP Address of the sender is greater
than the local primary IP Address, then:

o Cancel Adver_Timer
o Set Master_Down_Timer to Master_Down_Interval
o Transition to the {Backup} state"
