Parsing of "show vrf default detail" command is not working for IOS XR #142

Open icarus78 opened 2 years ago

icarus78 commented 2 years ago

Hi

I´m using pyats to get the interfaces per VRF and in global (default VRF) routing table. For VRF interfaces information the command device.parse('show vrf all detail') is working and I can get the list of interfaces for each VRF by reading the "interfaces" key for each VRF. It also works when using the command for one particular VRF, like device.parse('show vrf detail')

I will like to get the same list of interfaces as key for default VRF, but when running the device.parse command it gives the following error:

show_vrf_default_detail = device.parse('show vrf default detail') Traceback (most recent call last): File "<pyshell#272>", line 1, in show_vrf_default_detail = device.parse('show vrf default detail') File "src/genie/conf/base/device.py", line 524, in genie.conf.base.device.Device.parse File "src/genie/conf/base/device.py", line 551, in genie.conf.base.device.Device._get_parser_output File "src/genie/metaparser/_metaparser.py", line 312, in genie.metaparser._metaparser.MetaParser.parse File "src/genie/metaparser/_metaparser.py", line 292, in genie.metaparser._metaparser.MetaParser.parse File "src/genie/metaparser/util/schemaengine.py", line 415, in genie.metaparser.util.schemaengine.Schema.validate genie.metaparser.util.exceptions.SchemaMissingKeyError: Missing keys: [['default', 'address_family']]

It seems that it is not working because no "address-family" information is provided in the output of the show command

Is it possible to include the support for "default" VRF in the parser?

Regards

Hi @icarus78,

Thanks for reporting the issue. yes we can add support for "default", you are more than welcome to contribute . For it, there is the reference how to develop parser. And there are very nice YouTube video in the page by pyATS users. https://pubhub.devnetcloud.com/media/pyats-development-guide/docs/writeparser/writeparser.html

Kindly let me know if there is any other help needed.
