Need understands of CARP advertised Skew with Master and Slave process

[athisesanr]

Hi Folks,
     
      I just try to understand the master and slave election using carp advertised skew (To determine which physical or virtual machine has a higher priority, the advertised skew is used. A lower skew means a higher score)

Now question is, if i have 10 connection means i do have 10 virtual IPs, so by default I didn't configured any advertised skew even preempt disable on 2nd firewall. so how the carp master will be selected now ?

I could see in my two machine like FW01 and FW02 , that FW01 is always master even i try to reboot it may went slave and back to master once FW01 is up.

Then, now what is calculation behind the master selection if everything is default value in both machine ?


Thanks,
