Several physical network interfaces are bonded together
to one logical network device. The operating system has to support
this feature with a special bonding device driver. Consult your operating
system documentation how to configure interface bonding on your system.
Make sure that you configure high availability (high availability) bonding and ensure
your network interface cards support the interface failure detection
mechanism your bonding driver requires.
The following network setup applies:

Table 2. Advantages and disadvantages for a network setup for
physical network interfaces that are bonded together
Advantage
Disadvantage
Easy setup.
Operating system has to support interface bonding.
Redundancy in cluster communication.
Network interface hardware may has to support
interface failure detection (for example, MII link monitoring).
There is no need to move ServiceIP between devices
on the same node.
