Which IP label is used for HeartBeating?

Hi,

In HACMP, which IP label ( Service/ Boot/ Persisten) is used for send/receive Heartbeat packets in IP based Heartbeating?

ASAIK,
service IP: moves on all nodes inside the site. It's set inside a RG. It should be the IP clients will connect.
Boot IP: Is the IP of enXX which boot AIX. This IP is inside powerHA as ether type. I think this is for heartbeating.
Persistant IP: It's only for administration and managing powerHA. It's not part of any RG or services inside powerHA.

Hope this helps.
