Yes exactly Just On point that I’m not sure: what append if the client ask for a router update with —no-qos option ? Will it remove the QOS completely or just re apply the default value ?

Everything is working properly, but I’m wondering if there is a way to define a « default » QOS that would be applied on Router creation, but also when the user is setting « no_qos » on his router. On a public cloud environnement, we cannot let the customers without any QOS limitation. Thanks ! Damien
