节点一：
[grid@rac-one peer]$ oifcfg getif eth0 192.168.4.0 global public eth3 192.168.2.0 global cluster_interconnect eth1 192.168.1.0 global cluster_interconnect eth2 192.168.1.0 global cluster_interconnect [grid@rac-one peer]$
节点二：
[grid@rac-two peer]$ oifcfg getif eth0 192.168.4.0 global public eth3 192.168.2.0 global cluster_interconnect eth1 192.168.1.0 global cluster_interconnect eth2 192.168.1.0 global cluster_interconnect [grid@rac-two peer]$
5、删除192.168.2.0这个集群内部连接：
[grid@rac-two peer]$ oifcfg delif -global eth3/192.168.2.0
[grid@rac-two peer]$
6、在所有节点关闭集群和禁用crs服务且重启
