Check Point firewall entries in Cisco ARP table

Hi everyone

 

This is probably a simple one so apologies in advance. I have a Check Point 5800 HA cluster in a Data Centre and following some work on a Cisco Nexus, looked at the ARP table and saw the following for my firewalls:

 

Internet 19.23.13.140 0 001c.7f81.0908 ARPA GigabitEthernet0/0/0 (CP VRRP)
Internet 19.23.13.141 0 001c.7f81.13a8 ARPA GigabitEthernet0/0/0 (CP 1 interface)
Internet 19.23.13.142 0 001c.7f81.0908 ARPA GigabitEthernet0/0/0 (CP 2 interface)

 

Can someone tell me why CP2 MAC address is the same as CP VRRP? I was thinking that CP2 is acting as the master but would appreciate if this could be confirmed.

 

Many thanks
