[dev] FRR 10.2 Bug report - RIP/RIPNG distribution list fails to filter routes

[Russell Yount]

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.
