About that "as secure as possible" bit. If just one server gets
compromised that happens to have its IPMI port plugged into this
private network; the attacker may be able to pivot into the IPMI
network and start unloading IPMI exploits.
So caution is definitely advised, about security boundaries: in case
a shared IPMI network is used, and this is a case where a Private
VLAN (PVLAN-Isolated) could be considered, to ensure devices on
the IPMI LAN cannot communicate with one another --- and only
devices on a separate dedicated IPMI Management station subnet can
interact with the IPMI LAN.
