The header now I think that ffr continues to keep changing the ZAPI in the way. That's the right thing for them. But I don't think that keeping up with the changes of ZAPI is the right thing for GoBGP. It's endless waste of resource. I think that GoBGP could support one version that major distributions like Ubuntu lts but someone needs a cutting-edge zebra feature, he should use ffr. >> uses >> 32-bit VRF-IDs instead of 16-bit.
