If you're using a dedicated switch for cluster management, yes. Assuming
that IP1 and 4 are your public facing interfaces that will be holding the
service. You can use 2 and 5 for cluster management and fencing via IP3 and
6.

Or you can use crossover cables IP2 to IP6, and IP5 to IP3, but you will
have to run your cluster management over eth0, on the same interface that
you have your services bound to. Your choice.

But you can't reach the iLO interfaces using the other iLOs. Think of them
as "recieve only". It's up to one of the hosts to establish a connection to
them and issue commands.
