"OCR" HAS an invalid IP address Solution

Problem:
Clusterware PRC-1302: The "OCR" HAS an invalid IP address size
I encountered a problem with a cluster of 11.2.0.4  (rhel linux 6.5) on which we are trying to install Oracle Database 11.2.0.4. I note that the grid infrastructure has not been installed by me.
At one point of the installation error was encountered:

An internal error occurred Within cluster verification framework
Unable to obtenir network interface list from Oracle
Clusterware PRC-1302: The "OCR" HAS an invalid IP address size

Analize:

A check of the configuration of network interfaces with the command "oifcfg" shows that configuring interfaces in the cluster is not correct:

oifcfg iflist -p
eth0 192.168.0.0 PRIVATE
eth1 192.168.1.0  PRIVATE


oifcfg GetIF
*  192.168.0.0 global public
*  192.168.1.0 global  cluster_interconnect

PRIF-29: Warning: wildcard in network parameters can mismatch because Among GPnP profile, OCR, and system


Solution:

oifcfg setif -global  eth1/ 192.168.1.0: cluster_interconnect

oifcfg delif -global * / 192.168.1.0

oifcfg setif -global  eth0/ 192.168.0.0: public

oifcfg delif -global * / 192.168.1.0


Verfication and End Result:

oifcfg GetIF

eth0  192.168.0.0 global public
eth1  192.168.1.0 global  cluster_interconnect
