FRR 10.2 Bug report - RIP/RIPNG distribution list fails to filter routes
by Russell Yount 13 Jan '25

13 Jan '25

I attempted to upgrade some FreeBSD 14.2 systems from frr8 ( 8.5.6) to frr10 (10.2) both from the FreeBSD ports collection. I skipped frr9 due to a bug that did not initialize routes from the kernel on startup. The systems are VMs running under Proxmox virtual environment. The distribution-list functionality no longer works for both rip and ripng. The following configuration can reproduce the problem. I would be happy to test any proposed fixes for this. -- router rip network vtnet8 network vtnet9 distribute-list rip-dist-out out exit router ripng network vtnet8 network vtnet9 ipv6 distribute-list ripng-dist-out out exit access-list rip-dist-out seq 5 deny any ipv6 access-list ripng-dist-out seq 5 deny any -- Also I notice in frr10 the routes reflecting the interface addresses going to loopback interface display in "show ip route" and "show ipv6 route" route as a new local(L) route type. I assume this is intentional but thought I would mention it. -Russ Russell J. Yount <Russell.Yount(a)gmail.com>

Stop testing and updates for CentOS 7 / RedHat 7
by Martin Winter 09 Jan '25

09 Jan '25

Hi there, I'm planning to stop releasing any new CentOS 7 / RedHat 7 packages and stop the testing for it. - No more CI tests on CentOS 7 - No new packages for CentOS 7 / RedHat 7 (not even minor updates or security fixes) CentOS 7 is EoL for some time. So far, we still used it for build Redhat 7 / CentOS 7 packages, but there is now the time where repositories get removed or moved. As such, I think the work to maintain this in the CI Infrastructure and Release Build is too much and I'm considering abandoning it. This does NOT impact RedHat 8 or RedHat 9. Please reply if this causes any issues to you or have any other reasons why this should be reconsidered. Regards, Martin Winter
