How to configure public Nic sequence for RAC in Virtual Machine

In the virtual machine, when the RAC configures the public Nic sequence method, when the dual Nic is configured, one is public and the other is private, there is always an error, that is, through ipconfig/all, command to view the order of the network card, always the first private type of IP network segment. Solution: the root cause of this problem is that when the NIC is added, I added several NICs, which have their own order: Nic 1, Nic 2, Nic 3, nic 4. because I didn't know how many NICs are enough, I added four NICs directly. When adding the corresponding IP address, I did not notice that the NIC is the default 1 Nic.
The actual Nic name is in the default order. As long as the corresponding IP address is consistent with the default order of the system, the corresponding network segment can be set to public. After talking about it for a long time, let's look at my actual example. I hope it will inspire you. This problem is actually encountered during RAC. The first step is to view the current route information. This is normal.

In this way, there is a sequence between the two NICs, that is, the first Nic of the system without a serial number, if you want to set the IP network segment as public to public Nic, it is very necessary to set this network segment on this Nic. The other private CIDR block must appear in the second order. Then the corresponding Nic is the NIC with the suffix #3.
