multiple public ips on oracle linux

Summary:

How to assign more than two public IPs to a VM in OCI?

dear community

For load distribution reasons I require that my application go out to the Internet through more than one public IP address.

Example:

hostname Private IP address. Public IP address.
prod1 10.0.0.50/24 150.136.x.x
prod2 10.1.0.50/24 150.136.x.x
prod3 10.2.0.50/24 150.136.x.y
prod4 10.3.0.50/24 150.136.x.z

So the routing tables look like this:

[root@prod ~]# netstat -nr
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
