Hoi, As an update for the readers on this list (thanks to those, quite a few, who reached out with encouragement!), I have completed the Netlink Listener, which I documented in https://ipng.ch/s/articles/2021/09/02/vpp-5.html I took the existing code in pending gerrit https://gerrit.fd.io/r/c/vpp/+/31122 and added the ability to create the four standard types of subinterfaces using 'ip link add link ...' semantics, and then grafted over the routing table and FIB interaction code from Neale and Matt's previous work.
For the curious, you can see me loading OSPF and OSPFv3 and then loading a full IPv4 and IPv6 table in this screencast: https://asciinema.org/a/432943 Still hoping to make the VPP 21.10 cutoff (Sep 22), so anybody who can help complete the review and commit cycle, would be greatly appreciated. Thanks to Matt so far for his review on patchset #1 (of 3). groet, Pim On Wed, Aug 25, 2021 at 2:37 PM Pim van Pelt <p...@ipng.nl> wrote: > Hoi list, > > After completing task1-3 of the Linux CP work (see my mail from Aug 12 to > the list, I've now turned my attention to the Netlink Listener.
