Thanks for the link - that's really useful. I did re-order ip rules Friday (I think) - no change

In general, I would reverse the order of those commands to ensure no breakage. Also, 5.0 I think it was (too many kernel versions) added a new l3mdev sysctl (raw_l3mdev_accept). Check all 3 of them and nmake sure they are set properly for your use case. These slides do not cover 5.0 changes but are still the best collection of notes on VRF: http://schd.ws/hosted_files/ossna2017/fe/vrf-tutorial-oss.pdf
