IOSXE genie learn vrf - missing data

[dpecak]

I am trying to use VRF model in my testcases, but I cannot learn data properly on some devices.

Tested on

• Fab1-BC | Border device, Cat 9300, IOS-XE 17.5.1
• Fab1-E | Edge device, Cat 9300, IOS-XE 17.5.1
• Fab1-WLC | WLC controller device, Cat 9800, IOS-XE 17.3.3

No exceptions during genie learn process

(venv) [root@dpecak-centos-docker pyATS]# genie learn vrf --testbed-file sda.yaml

Hi @dpecak,

Fab1-BC: Here the parsed output have "route_targets" and "route_distinguisher" in each vrf. This is the reason you were only getting output for this device.

Fab1-E, Fab1-WLC: These two devices does'nt have the above data that's why you were not able to learn the data properly. In this case, we have added support for two new data "description" and "table_id". Now you should be able to learn it from parsed output. The fix will be available in next release.
