If each Bonding group connects to a different system (segment) and one of the ports become inaccessible,
the other Bonding group port continues the connection.

NIC-CA#0
If the other port also becomes inaccessible, the failover function is executed, and the IP address is taken
over by a port of a different controller. In this case, the other Bonding groups (B and D) are not affected by
this operation.
