Martin: Does this mean if the I2RS model provides additional functions that are not a base configuration model that the xpath should just work?
Xpath1- Config - ISIS Yang model that configures Xpath2 - I2RS ISIS empheral - inherits all the configuration state ____ I2RS ISIS actions - report on the interface changes on ISIS L1 interfaces Is my I2RS ISIS model a combination of the inherited state and the I2RS actions?

The quoted text is for the error-path. For the filter, rfc 6241 says (p 67): o The function library is the core function library, plus any functions defined by the data model. /martin _______________________________________________ i2rs mailing list [email protected] https://www.ietf.org/mailman/listinfo/i2rs _______________________________________________ i2rs mailing list [email protected] https://www.ietf.org/mailman/listinfo/i2rs
