Cumulus Networks is invested in the VRF solution, and we will be here
for the long haul. We want a feature complete, performant and stable
solution for open networking. My preference is for a built-in solution
rather than a bolted on one and I am trying to do that by engaging the
community and getting feedback early for decisions and preferences.
As for the details, I am finishing IPv4 integration now. Basic VRF-lite
situations work great and I have tested a few IPsec and MPLS setups as
well. I have one more patch to address Tom's comment regarding
udp_sendmsg; I need to verify it works for fragmentation and I'll push
it out. After that I will start on IPv6 next week.
