OCI: How to restrict Egress access to OSMS service only ?

Applies to: 

Oracle Cloud Infrastructure - Version N/A and later

Linux x86-64

Goal

The purpose of this KM is to explain the steps to allow Egress rules to OCI specific Services. i.e  OSMS

Solution

It is possible to allow access all the Oracle IAD services but not possible to restrict to specific services like OSMS.

Refer to Oracle documentation about Service CIDR Labels.

In the egress, rule set the "Destination type" to "Services" and selects "All IAD services in Oracle  Sevices" in the "Destination Service" section.
