Hello Community colleagues!
Wondering if anyone is experiencing the same errors when trying to read with ydk-py with an OC Interfaces filter from a JunOS (MX 19.4)
Seems to me that unlike the IOS-XR devices i've tried before this, JunOS have some openconfig model representation mismatch with the YDK bundle, at least for the addresses element within interfaces. Also, unlike IOS-XR they don't list the OC yang models in the capabilities list when opening the netconf session which also creates other issues for writing config as well... I've managed to solve that by using pre-defined OC Repository() objects, but this doesn't seem to apply for read ...
For the read part this is what I'm trying initially:
>>> from ydk.services import NetconfService
>>> from ydk.types import Filter
>>> from ydk.models.openconfig.openconfig_interfaces import Interfaces as oci
>>> from ydk.models.openconfig import openconfig_network_instance as oc_netins
>>> netconf = NetconfService()
>>> ifaces_filt= oci()
>>> filters = Filter(ifaces_filt)
>>> crud = CRUDService()
>>> netconf_output = crud.read_config(provider, filters)
And this is the response:
