When firewall configuration is two-node cluster hot backup A-P mode, the configured main and backup device seize overturn. The main device become the backup one，the backup device become the main one, and always appear the following prompt：
HRP NOTICE: Some local vrrp standbys configured as master don't accord with vrrp standbys configured as slave on peer device!
Input command on the main device：display hrp state
Use command to view currently hrp state，the ports that join the VRRP group which is down，there are two ways of dispose approach :
1.Make the port up
2.Make the port out of vrrp group
Based on attention we can analyze out when preemption, as a port of the main device in the VRRP group is down，HRP protocol negotiation that the main device is down，so the main become backup and the backup become main.
