Nexthop/nexthop groups question
Hi folks, Cumulus people implemented nexthop objects/nexthop groups [1] in Linux kernel some time ago. These changes allow for more efficient communications between kernel and userspace w/ wide multipath & large amount of routes. Initial support landed [2] in FRR in 2019 and has notably improved since then. Are there any plans to support this functionality in bird?

Hello! Yes, we definitely want to support it, yet last time when we were talking about it, it was still unstable. It is good news that it really has come in, we'll study it and most likely also implement it. Thank you for pointing this out. Maria On September 22, 2020 11:08:02 PM GMT+02:00, "Alexander V.

Dear Programmers, does it imply, that upcoming Linux nexthop objects/nexthop groups support in Bird will be automatically compatible also with just committed FreeBSD new routing kpi[1] ? [1] https://reviews.freebsd.org/D24232 -- Marek Zarychta
Hello! Wow, you've decided to drop the old routing KPI. We were wondering when this is going to happen. Definitely a good idea, I must say. From the overview, the new KPI looks to be pretty similar to Linux nexthops, so it may be quite easy to implement this new KPI together with implementing Linux nexthops. Thank you for pointing it out, this is a very useful note from you. Maria On October 3, 2020 3:28:41 PM GMT+02:00, Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> wrote:
