There is no generic model for this in RFC 7223, but there are three options: (i) use YANG 1.1 require-instance false (ii) require the underlying interface to be configured (even if it is system-controlled) or (iii) use an implicit reference. /martin _______________________________________________ i2rs mailing list [email protected] https://www.ietf.org/mailman/listinfo/i2rs
