RHEL, ip route reports "RTNETLINK answers: No such process"

Issue

• Team, we have 3 adapters , we trying to add the adapter ethX, which is not working and giving error no such process.
• Adding a route for a remote subnet will not work. The ip command will return RTNETLINK answers: No such process. That is because the netlink code cannot find a local interface with an IP address that matches the subnet in the command.
