[INS-41107] The interface (eth1) chosen as Public or Private is not on a shared subnet. Nodes not defining are: [rac2]
Network interface subnet are not same for both the RAC nodes
Cause – The Public or Private interface on the nodes indicated are on a different subnet than the ones used on other nodes.
Action – Ensure that the specified Public or Private interface share the same subnet across the nodes.

Solution:
Contact your network admin
identify the mac address of both nodes nic interface card
configure the ethernet interface to the same subnet!
Reconfigure ipaddress for nodes
