Hello there,

The self connects use case follows the same approach as enterprise use cases. However, in self connect you are connecting between your own assets deployed at Equinix. Unlike the cloud servic provider workflow, in self connect and enterprise workflow you don't have to perform any additional steps to start network traffic as Equinix handles it for you.

Refer to https://developer.equinix.com/docs?page=/dev-docs/fabric/getting-started/fabric-v3-apis/connect-to-myself  to know the steps involved to create a self connection.
