If you want to hide your cluster vip for some time, you can play with

#ip link set eth3 arp off

But if your vip is on a virtual interface or a secondary ip, #ip link; can’t help you.

You can just

#sudo yum -y install arptables_jf
#arptables  -A IN -d $YOURVIP -j DROP

The syntax mimics iptables, so

#arptables-save ; # list rules
#arptables -F ; # flush rules
