Route filtering by route distinguisher

[Jon Langemak]

Thanks!  I had looked at the repo and saw those references but I’m still unsure how to reference them as part of a filter.  I’ve tried just comparing it to “rd” or “vpnrd” but have been unsuccessful. In the test examples they are referring to it as an attribute of a route that they are instantiating.
