NIC Bonding module is available from 24.12 and higher versions. If you have already installed bonding driver, you can configure the 118 and 119 subnets to a single bondIP (120.x) and use the VIPCA to configure the Virtual IP. In this case your eth0 and eth1 will be a new bonded interface and can be used against interconnect failures.
