IOS-XR show route vrf {vrf} ipv4 {route} UnboundLocalError #123

Closed vishnuo-lab closed 4 years ago

vishnuo-lab commented 4 years ago

I am getting a UnboundLocalError sometimes when running this parser. Seems to happen for BGP external routes but not 100% sure. This is on iosxr ASR 9912 v6.5.3.

Hi @vishnuo-lab ,

We fixed the issue and a new package has been released with the fix. https://github.com/CiscoTestAutomation/genieparser/blob/master/src/genie/libs/parser/iosxr/show_routing.py#L231

Could you please run the following command and try again to see if it works?

Please try and let's know if there is an issue.

Thanks, Irene
