From What's New in Oracle Grid Infrastructure: Redundant Interconnects for Oracle Clusterware. Но это совершенно не обозначает возможности вообще отказаться от OS bonding. Возможность redundant interconnect относится только к clusterware, но не к Cache Fusion.

From internal mail list:

"However that statement is not very true in the sense that even though clusterware can use multiple network interfaces, the database cannot so for now the DB has to rely on externally implemented bonding solution. This may be improved in a future release"
