Re: [i2rs] Kathleen Moriarty's No Objection on draft-ietf-i2rs-yang-l3-topology-08: (with COMMENT)

I do not understand your question, but the answer is likely 'no'.

See Martin's email, perhaps that one helps.

In RFC 7223, you can configure an interface that is not currently
present. An interface is identified by a name and the interface
configuration sits in the configuration datastore. When an interface
starts to exist (e.g., a line card is inserted) that has a matching
name, then the interface configuration with the same name is applied
to it. This is RFC 7223 style pre-provisioning.
